| The picture shows all of the packets holding (78) Different Audubon Bird Record Cards With Envelopes in this lot. The front and back of two different sample cards are also shown. The packets each contain a numbered set of (10) cards. The packet sets are lettered: A, B, C, D, E, F, G, & H. All of these are complete with the exception of set D which is missing two cards. The names of the birds that go to each set are on the envelopes. There are too many birds to list here, but they are all different. Each card has a nice colorful picture on the front and information on the back. Also on the back is a clear square record (see picture) that plays the sound of that particular bird. Originally these came with a small player that the card goes into to hear the sounds. I am afraid that I do not have the player to include here. There are (3) instruction cards for the player that are included but not pictured. The bottoms of the cards are marked as follows: JOHNSON / DOLE 1977.
