This box contains "Everyday Greetings - Appealing cards that kiddies love". It is the Tiny Tots collection, and originally contained 16 cute and colorful cards for children.
Now, this well worn box (6 1/2" x 4 1/2" x 1 1/2") still contains 11 unused cards with envelopes. The cards are about 4" x 6", and each contains a cute message inside. The front of each card is shown in the photos, and all sides of the bunny card are shown.
I believe there must have originally been 2 each of 8 designs. Now, there are 7 designs present; 2 with the puppy, 2 with children painting, 2 with carousel, 2 with elephant, and 1 each of the cook, the Indian and the bunny - 11 cards in all.
