Double impressionexamples of the black- on- blue adhesives are designated6LB5c, and double impressions of the black- on- green adhesivesare given the designation 6LB5e.At the beginning of 1843 the U.S. City Despatch Postissued a black- on- blue- green adhesive on surface coloredpaper (6LB5). It is at this time that they also changedto a single circle datestamp. The double circle datestamphad been in use for less than a year. The recording of thetime in the datestamp was evidently no longer important,and it would typically not be recorded in the new datestamp.It is quite likely that delivery was made at eithernine am or one pm, and it was deemed unimportant tonote the time. Over the next four years through 1844,1845 and into the fall of 1846 the black- on- blue- greenadhesive would be the “workhorse” with various shadesof reprinting.The black- on- blue adhesive (6LB5b) does not appearuntil the fall of 1844 and is a very striking color. There areonly two examples of covers with multiple black- on- blueadhesives (6LB5b). One cover has four adhesives and isaddressed to Athens, New York, and the other has threeadhesives and is addressed to Ridgefield, Connecticut.This black- on- blue color adhesive continued to be useduntil the U.S. Despatch Post closed in November 1846.The black- on- blue- green adhesive (6LB5) is also recordedon cover with the New York Provisional 9X1d.Double impression errors on glazed surface paperadhesives occurred in three different colors, Black/bluegreen, black/blue, and black/green. A double transfer is acondition of a transfer on a plate that shows evidence ofa duplication of all or a portion of the design. Occasionallyit is necessary to remove the original transfer froma plate and enter the relief a second time. When the finishedre- transfer shows indications of the original transfer,because of incomplete erasure, the result is known as adouble transfer.Last but not least there is a black- on- pink adhesive(6LB6). This stamp is on a cover dated April 7. The U.S.City Despatch circular datestamp on this cover is a doubleline circle which leads to the conclusion that the year dateis about 1843. There is only one recorded example of thepink adhesive. It is shown in Figure 7.Figure 7. A black- on- pink unglazed surface colored adhesive 6LB6, on a cover front dated April 7, (1843). Thisis the only recorded example. The datestamp is the double circle which was not in use after 1843. From the collectionof Larry Lyons.
