In the mid-20th century, families had a lot of fun designing holiday greeting cards in which printers would cut and paste photographs, often combining them with hand-drawn illustrations. Just like today, their pets were considered part of the family, and often were the most photogenic member.
Check out a collection of holiday greeting cards featuring pets, gleaned from the extensive vintage photo collection of Robert E. Jackson. While dogs and cats are front and center, they aren't the only beloved family pets that made it to the Christmas cards. There's a monkey, a chicken, a couple of horses, and a lion!
