The first images I find SC# 2515 (11.5 perf and 2516 (11.5 x 11) but this stamp is 11x11. Is it possible there is another I cant seem to find? Could this be a error stamp of some kind?
Second image is a single stamp (Vesper sparrow) from the series "#4352 – 2008 42c Nature of American: Great Lakes Dunes". I cant find a scott number for the individual stamp. anyone know its number?*** Moved by Staff to a more appropriate forum. ***
