6 Vintage Porcelain Cups Mugs with Bird Audubon Images Japan

6 Vintage Porcelain Mugs with Bird Audubon Images Japan. There are 4 different images with 2 duplicates. Images are in excellent condition. Two of the mugs have blemishes. One has a small chip at the rim which doesn't show well in the pics. The other has what appears to be a burn mark at the bottom edge. No other chips, cracks or crazing. All have the number "9056" stamped on the bottom. There are no other markings. I believe them to me made in Japan because of sets I've seen with the same birds having Japan stamps. 8 oz. capacity each. 3" tall x 2 3/4" wide not including handle. Due to weight, please do not bundle with other listings. Thank you!! hg q
