1950 Audubon Birds of America (50 Selections) retailer

This is a beautiful collection of prints from the Audubon Society. There are suppose to be 50 prints but this set is missing one. Also, 2 of the prints look like someone drew on them. I have shown those two pictures. The rest of them are gorgeous! Descriptions of the birds are on the back of each photo.
There are minor imperfections on the prints. The booklet it self is ok..three of the corners of the box are split . The prints are still contained nicely. It's a great collection of prints. They measure retailer They measure 12x9” and the booklet measures approx 13x9”.
