Prior to the present invention, draftsmen and/or architects and/or engineers utilizing the latest technology of utilizing a computer drawing-mouse or digital tablet-cusor while concurrently comparing blueprints or the like on a monitor screen to and in comparison with exhibit-drawings and in thee concurrent use of the mouse or digital tablet-cusor to superimpose data viewed from the drawing-exhibit onto the computer screen blueprint, have been faced with the heretofore difficulties and/or hardship and unsolved problem of inadequate ways of simultaneously handling and/or temporarily mounting/supporting all of the papers while using the computer mouse or digital tablet-cusro. Normally and often the exhibit-papers and/or documents are of large and varying width and length sizes and shapes not readily adaptable to conventional document holders. As well, frequently and normally such exhibit-papers and/or documents are in the nature of non-rigid paper not readily supportable. Paper weights and/or tacks have been less than satisfactory alternatives and conventional document holders conclusively are not functionally capable of adequately doing the job. Because of the necessity of manually handling the mouse or digital tablet-cusor when making drawing and/or notation changes to the blueprint image on the computer screen, together with visually making reference to particular points on the drawing-exhibit in comparison to the image viewed on the computer screen, the person's mere two hands while maintaining his concentrated attention to the task of making needed entries onto the computer monitor's memory as viewed on the screen, has proven to be extremely difficult and awkward and not readily possible devoid of excessive strain, consumption of excessive time and experiencing of distractions from optimal concentration and attention to the crucial matters being attended to. Moreover, in arriving at the present invention, it was noted that no easy solution existed for mounting, suspending or hanging a document support on computer monitors, it being additionally discovered that notoreously when moving from one computer monitor to another either within the same or different desks and/or offices, the width and height dimensions of word processor and/or computer monitors vary considerably from one monitor to another. That fact accounts for prior art devices heretofore having been rigidly mounted onto monitors by screws or adhesive or the like, as above-noted.
