A Funny Astronaut Postcard, Out Of the World Deal

You don't have to go this far . . .
- - - see us for an out of the world deal.

This is the oddest advertising postcard ever!  There is no company listed.  There is no store, no nothing.  So if I want an 'out of the world deal' who do I go see?

In very very small letters on the bottom it reads C 1965 Pramar Adv. Spec. Co. Yonkers N.Y.  But this is who had the copyright on the postcard.

This is postmarked in 1973.  Below is a scan of the back of the card.
