Show cards were issued for many stamp shows over the years. Based on what I have found, they are much harder to come by mint then they are cancelled. Here is the card issued for Philexfrance 82 (SC3). I have only seen it FDC, not mint. So, if you have an extra mint one, let me know. I am also looking for Belgica 82 (SC4), Finlandia 88 (SC20), World Stamp Expo 89 (SC23), and Capex 96 (SC35).
