Back in tne 90's, for about 10 minutes, POGs were all the rage. Basically a cardboard disc shaped like a milk bottle cap liner.
They originated in Hawaii, POG being an anacronymn for passionfruit, orange and guava. Some sort of game was played with the discs (for more info and history, try here: http://en.wikipedia.org/wiki/Pogs). Starmark Entertainment tried to cash in on the craze with sets of their own. Most of the sets were based on superheroes. I tried be a little different.
