General Dynamics Astronautics space cards / late Sixties
Probably issued by the GD publicity folk to celebrate their continuing funding from Washington for the space race. I would guess some time in the late sixties. Nicely produced in a standard card size with a protective varnish on both sides. Fifty-two cards plus two jokers - one with Superman.
An additional card says: These space cards tell a story - the story of America’s man-in-space programs. The hearts deal with the human element, the clubs portray the sciences, the spades show products and the diamonds depict modern aerospace management without which the other three elements could not be successful.
