VINTAGE Avon Set of 2 Bird Collectible Plates Bluebird & Yellow Breasted Chat

Set of 2 vintage decorative plates by Avon. They depict birds of the USA on the front, have a write up about the bird on the back and a gold rim. The back of the plates state they are a special edition awarded to Avon Representatives. In researching these, I believe they date to 1975. One plate depicts the Yellow Breasted Chat, and the other plate depicts the Bluebird. The design of the plates was created by Don Eckleberry. The Bluebird plate also has a USA stamp on the back. Please see photos for approximate dimensions: 10.25 in diameter. Very good vintage condition, no chips, cracks or crazing. The Bluebird plate does have a tiny mark on the back as shown in last photo.
