|Arm & Hammer Useful Birds, Series 3, Advertising Cards|
This 30-card set of "Useful Birds of America, 3rd Series" was issued to advertise Arm and Hammer Baking Soda in the early 1900s. Each one features a beautiful image of a different bird on the front and a short ad and brief description of that bird on the back. They measure 2-7/8" by 1-7/8 inches. I am offering these 30 cards individually so that collectors will be able to fill in the missing parts of their collection. All cards are in excellent condition with no tears or creases unless noted.
