1851, 2-cent local <i>Priest's Despatch</i> <a href="//commons.wikimedia.org/wiki/Stamps_of_the_United_States" title="Stamps of the United States">US postage stamp</a>, imperforate on unglazed yellow paper.  Contrary to the image name, judging from the letter shapes, this appears to be a Scott #121L3, though it is likely that it is a forgery.
