what are the blue boxes at the post office
Post box [15] In 1971 the United States Postal Service changed mail collection boxes to the current USPS Dark Blue with contrasting lettering.[12][15][16] The coming of the automobile also influenced U.S. mailbox design, and in the late 1930s, an extension chute or "snorkel" to drive-up curbside collection boxes was adopted.[11]
Postage stamps and postal history of the United States It would be private enterprise, however, that brought stamps to the U. S. On February 1, 1842 a new carrier service called "City Despatch Post" began operations in New York City, introducing the first adhesive postage stamp ever produced in the western hemisphere, which it required its clients to use for all mail. This stamp was a 3Â¢ issue bearing a rather amateurish drawing of George Washington,[9] printed from line engraved plates in sheets of 42 images. The company had been founded by Henry Thomas Windsor, a London merchant who at the time was living in Hoboken, New Jersey. Alexander M. Greig was advertised as the post's "agent," and as a result, historians and philatelists have tended to refer to the firm simply as "Greig's City Despatch Post," making no mention of Windsor.[10] In another innovation, the company placed mail-collection boxes around the city for the convenience of its customers.
