My impression is that Rocco Mastroserio penciled the first page of "The Mirror of Mystery"; Dick Giordano certainly did the remaining three. What do you think?

Interestingly enough, there's an ACG story ghosted by rather than for Sal Trapani. The art on the other new story in Unknown Worlds 53 is credited solely to Bob Jenney, but Trapani is inking Jenney's pencils.
