GLASSES/ROCKS-Style of Artist Ashby-Tennis Cartoon Characters-Humorous-Set of 4

Set of four rock style glasses. These are done in the cartoon style of a cartoon artist. I believe it is Ashby - they are not signed. Each glass has unsigned drawing of different funny tennis scenes. They are all done with a sense of humor. There are two with a gold background and one with green and one with orange. They have a gold rim on the top that shows some wear. They are a cute set of glasses. I also have 2 other glasses listed separately. One is a duplicate of one of these glasses and the other shows some wear on the image.
