Invisible Dick featured in the Sparky, in the comic strip. Dick Dixson was given a souvenir of a space flight by his father, who was an astronaut. The souvenir was an electric torch that had formed part of the equipment of a space capsule in orbit. But Dick discovered that mysterious rays in space had affected the torch. It now shone a black beam instead of a white one, and anything it shone upon became invisible for a time.
