I have this black and white pack, dated 1993, from One Shot Press

Says on it, Trading Card Set 1, Contains cards 1 to 6. This originally sold for $ 5, according to what it says on the pack

Did they only do 6 cards ? Was there a Trading Card Set 2 or any others ?

Answering the call 8 years later...it appears that was the only set. It also appears that the same six cards were inserted in the comic issue, "The Captain's Jolting Tales #3.

PCE2008 notes that there were two versions of the cards - all with prismatic borders and/or backgrounds. The prismatic effect was made up of either tiny squares or circles. The cards in the pack had squares or circles so it appears you got six of the same cards that were in the comics.

I just happened to be reading about the comic in a back issue article of Wizard and it mentions the cards. I looked at what was on Ebay too. This would be of interest to Todd.
