Vintage Christmas Placemats

Cindy Character, Copyright Grand Award, Boston U.S.A. MCMLXXV (1975)

I have a set of these four laminate placemats. All with different Christmas images, featuring a character named Cindy. They were wasting away in my mother's basement and I couldn't resist them. I've been trying to find any information on the character and if she's been used for anything else, greeting cards, figurines, etc. because I think she is so adorable ( and the cat is cute too lol ) The only information I have is listed beneath the picture and that's what was given on the back side of the mat.
