A recent article on baseballcardpedia.com featured this set. I'd never heard of it before. There was only one Phillie in the set and I got lucky that it was available on eBay.
The cards were produced by Topps. They have a light gloss, front and back. The back features Schilling's 1992 pitching results. Note that early in the season, he was pitching only a few innings in each game. It's hard to remember now, but Schilling was a relief pitcher before he came to the Phillies. He appeared in 42 games in 1992 but only 26 of those games were as a starter.
When I last looked there were 5 individual cards and one set available on eBay.
