Church & Dwight Co. "Useful Birds of America"

Artist is Louis Aggassiz Fuertes. The cards are from Church & Dwight Company 10 Cedar St. New York, New York. Each card has the bird name on the front and information about the bird on the back. These cards measure 1 7/8" x 3" . Originally there were 15 cards in the series. I am missing the Bobolink, the eastern Phoebe, and the Downy Woodpecker
