Lovecraftian advertisement for keeping humans as pets

The poster features an image of a naked human woman trapped in a large glass jar with a twig and a leaf, depicted as if in a sepia magazine spread. For those of you who don’t read the language of the Great Old Ones, I will translate:

Start your Human
Collection today…

Humans make great pets.
You can sit and watch
them for hours.
Just remember to poke
holes in the lid and add
a twig or leaf to mimic
their natural habitat.

If you want to keep your
Human alive for more than
a day you’ll need to put it
in a full environment and
provide food and water.

Humans are trainable.
They can be taught to
Speak on command and
will Faint when threatened.
Can be kept with other
Humans in a large habitat.
