     FULL DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to FIG. 1, the route truck assembly is shown in its flat or knockdown position for shipping purposes. 
     As shown in its flat position, the corrugated fiberboard has factory applied fold lines shown as dashed lines and factory applied cut through portions shown as solid lines and normally designated by the letter C. 
     The main sections are shown as defined by dashed score lines therebetween, said score lines allowing a folding of the main sections and attached flaps and tabs relative to each other. The score lines are factory preformed utilizing known steel rule die technology. It should be noted that the solid line sections designated by the letter C represent factory cut through portions to facilitate, for example, the formation of wheel sections 21, flaps 50a and 50b and tabs 20a upon appropriate assembly folding of the device. 
     The main body portion of the route truck is shown in its flat or knockdown position in FIG. 1 as comprising a rectangular central section 10 which forms the top of the route truck upon assembly, truck side wall sections 20 attached to both sides of central section 10 with score lines formed therebetween, truck bottom wall sections 30 formed outwardly of the side wall sections 20, end panel sections 40 which form a central vertical supporting strut upon assembly. 
     As further shown in FIG. 1, central section 10 has a truck rear panel section 50 formed on one end thereof, the rear panel section 50 having flaps 50a and 50b and a slotted tab element 51 formed on the sides thereof. 
     Tabs 20a and 20b are formed as a part of side wall sections 20 and serve to provide support for the upper cab assembly of FIG. 2 and to provide closure means to give the assembled truck a finished and attractive appearance. A slotted assembly flap 60 is shown on the upper edge of the central section 10. 
     As shown in FIG. 2, the second piece of the invention, i.e. the upper cab assembly, comprises a rectangular grill panel 70 having flaps 70a and 70b formed on both lateral sides thereof and a slotted flap means 71 formed along a lower edge. Hood panel 80 is formed along the upper edge of grill panel 70 via the score line therebetween. A windshield panel 90 is formed above the hood panel 80 and has flaps 90a and 90b on the sides thereof as shown. 
     The cab top panel 95 is formed above the windshield panel 90 and has a slotted flap means 98 formed on an upper edge thereof. 
     The unique constructional design may best be illustrated by describing the method of assembly of the route truck of FIGS. 1 and 2. 
     The two end sections 40 are manually folded inwardly to a position of edge aligned relationship wherein the outer edges 41 are in contact with the inner roof section 10 of the route truck. The score lines shown between main sections 10, 20, 30 and 40 permit the above first folding step. 
     In this position, an elongated rectangular tube is formed with cut out wheel sections 21 depending therefrom. The two end sections 40 are thus positioned in the middle of the elongated rectangular tube in a vertical position after the above first folding step. 
     In the next folding steps, flaps 50a and 50b are folded inwardly ninety degrees as is tab 51. The truck rear panel 50 is then folded inwardly ninety degrees such that flaps 50a and 50b are positioned interiorly of the truck side walls 20. The slot means 58 formed as a part of tab 51 is then in position to be slid retainably over the vertically positioned end sections 40. 
     The rear portion of the route truck assembly is thus completed. 
     The front portion of the truck is assembled by first folding over flap 60 and tabs 20a and 20b ninety degrees along the score lines shown in FIG. 1. 
     The upper cab assembly of FIG. 2 is then added by positioning the slot means 78 of flap 71 over the areas 42 of the panels 40. 
     Grill panel 70 is then folded upwardly such that its flaps 70a and 70b lie interior of the truck side panels 20. Hood panel 80 and windshield panel 90 are then folded over such that side flaps 90a and 90b  are positioned to the rear of tabs 20b and interior of the truck side panels 20. 
     From this position, cab top panel 95 and its attached flap means 98 are folded over in such manner that the slot means 99 of flap 98 fits into the pocket channel 43 formed in the end panels 40. It should be noted that slot 61 of flap 60 would also have been previously fitted into said pocket channel means 43. 
     It should also be noted that the perforated score line shown between panels 80 and 90 allows the single outward fold of the assembly, i.e. it permits the windshield panel 90 to be appropriately angled relative to the hood panel 80. The other socre lines shown in the assembly generally permit only an inward fold of their respective adjoining sections. 
     In the assembled position, hood panel 80 rests on edges 44 of the end panels 40 while windshield panel 90 and cab top panel 95 rest on edges 45 and 46 respectively. 
     Suitable printed promotional material, such as an advertisement for a particular product, may be applied to the corrugated material in its flattened position before shipping utilizing known printing technology. 
     It will thus be appreciated by those of skill in the art that an easy to assemble yet durable and attractive miniature route truck promotional aid is achieved by means of the factory cut corrugated fiberboard design. 
     The flat initial shape of the component parts yields a product which may be shipped flat and therefore distributed to purchasers in a most efficient and cost-effective manner. 
     The engineered shapes disclosed are of course critical to both the ease of assembly of the device and the durability and attractiveness of the assembled product. 
     While there has been illustrated and described what is at present considered to be a preferred embodiment of the present invention, it will be appreciated that numerous changes and modifications are likely to occur to those skilled in the art, and it is intended in the appended claims to cover all those changes and modifications which fall within the true spirit and scope of the present invention.
