Now here we have the New York Post Office, or not, because this card was issued in 1889. The truth is that they did not get the date wrong, for this is the first New York Post Office, known as City Hall Post Office and Courthouse, and located along Broadway in Lower Manhattan. That started to be built in 1869 but was not finished until 1880. It was never popular, though it stayed in place long after our building had superseded it, and was only demolished in 1939.
This set is listed in our World Tobacco Indexes, under Duke section 1, covering "regular coloured issues in U.S.A." as :
POSTAGE STAMPS. Sm. Real postage stamps affixed to series of cards "illustrating mail matters..." Unnd. (50). See ABC/85. Ref.USA/85
A. Centre wording on back "A Foreign Postage Stamp", (a) with (b) without printers` credit at base.
B. Centre wording on back "A Genuine Foreign Postage Stamp"
The only difference between the vintage and modern editions is that the text to A. now reads : "A. Centre wording on back "A Foreign Postage Stamp" (a) with printer`s credit (50) (b) without printer`s credit (only 25 subjects believed issued).
