This set of North American Birds Thick Trading Cards is a must-have for any collector. With a complete set of 50 cards, this set includes a variety of non-sport trading cards featuring the beloved North American Birds franchise. The cards are perfect for trading or collecting, and are sure to impress any avid bird enthusiast. The set includes a range of different cards, all renderings from an artist (artist unknown), with the bird name along the bottom and a bold number in one of the lower corners. The individual cards measure approximately 5.5? x 3.5? and each card is thick and durable, ensuring that they will last for years to come. They are in good to very good condition (not Mint), some have a bit of staining, many have very slight corner dings, but nothing atrocious. If I had to guess I would say these are from the 1950s or 1960s, and they could possibly be from a game of some sort. The backs are blank. Whether you're looking to add to your collection or trade with other collectors, this set is the perfect addition to any collection.
