Vintage COBY Pet Set Greeting Cards

This set is from the 1970s or earlier. I know this because when I was a baby I was given the card with the shaggy sheep dog! This is a complete set of 10 cards however, there are only nine envelopes. The cards are perfectly good, the box has some denting and damage and a small hole. See photos please. These cards are large, approximately 8 x 10, I don’t have my ruler handy, again, please see the last photo. On the box, they refer to them as “giant“. There’s a variety of occasions inside the cards. Personally, I think they would just look amazing framed up on a wall in the right room. 😍
