Five Adams "Birds of America" plates - White stoneware plates have embossed leaf rims and the center of each is decorated with a different American bird transfer taken from engravings based on the drawings of John James Audubon:
One plate has some light, unstained crazing across the top. That is the only flaw in the entire lot and it is minor. The set displays beautifully.
The back of each plate is stamped as shown in the photos. (Four plates are stamped with first Audubon portrait mark Audubon portrait. Only Baltimore Oriole plate has the second mark)
