This is one of the fifty cards that I came across the other day. The cards have the painting of a bird on the front and on the back it list a description, classification, scientific name and range. The title card states "50 Winter Birds of the Northeastern United States from color drawings by Allan Brooks, published by the National Association of Audubon Societies, 1974 Broadway, New York City. Sold in sets Price $1.00."
I have truly enjoyed both the paintings and the information on the back of each card.
The kitty justice is that you can learn a lot from a dollar set of cards.
