According to this advertisement I found in 1966’s Amazing Spider-Man #44, you could apparently buy a “darling monkey” for $18.95.
The ad goes on to say:
The Squirrel Monkey makes an adorable pet and amusing companion. Show it affection and enjoy its company. Almost human with its warm eyes, your family will love it. These YOUNG monkeys grow about 12 inches high. Eats same food as you do (even likes lollipops, simple to care for and train. FREE cage. FREE leather collar & leash, monkey toy, and instructions included. Live delivery guaranteed. Only 18.95 express collect. Mail check or money order for $18.95 to: Animal Farm, Dept. MA-25 Box 1042, Miami Beach 39, FLA.
Now I understand some strange stuff went on in the 60’s but selling baby monkeys to random comic reading kids is just plain terrible. In fact, “squirrel monkeys” are now listed on the endangered species list. Of course I’m completely ignoiring the seahorses advertised above, somehow that’s slightly less disturbing.
