1851, 2-cent local Priest's Despatch <a href="//commons.wikimedia.org/wiki/Stamps_of_the_United_States" title="Stamps of the United States">US postage stamp</a>, imperforate (Black on unglazed blue paper). Contrary to the image name, judging from the letter shapes, it appears that this is a Scott #121L5, though it is likely that this is a forgery.
