DC Comics, Superman, Hulk, Spiderman, ballpoint pens

Wow! Look at this amazing premium! Never used, and only out of the package to photograph. DC Comics, Spiderman, Incredible Hulk, and Superman, ball point ink pens, in a celophane "Thank You" package. Date on pens are 1978. What a cool collectible. Usually these are only found as a single, and never with the package!!
