This advertisement appeared in Candy issue #40 published in 1953. It was also in quite a few other comic books of that period.
"EVERY BOY AND GIRL LOVES THESE CLEAN LITTLE PETS, DELIVERED HEALTHY AND SAFE IN A SPECIAL MOSS-PROTECTED PACKAGE.
Here's one of the most exciting toys you've ever owned. Just think -- a baby turtle all your own. What's more, a real growing garden to keep him in, a garden you plant and grow all by yourself. You can teach him to recognize you when you feed him. Watch him swim - see how he pulls his head and feet into his shell when he is frightened. You can have turtle races - you can make a little house for him to live in - and all the time you can watch how the lovely, soft grass grows - see and smell the beautiful flowers. You'll amaze your friends with how much you know about animals and plants.
A real growing Rock Garden - about 100 square inches of sweet grass and bright lovely flowers - for you to care for."
All this was only one dollar. How many of these poor creatures survived and of these how many ended up in the local pond?
