Nymph
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
Nymph is an adult entertainment magazine containing scantily-clad, yet tasteful, photos of women. Reilly possesses one, and when he is killed this copy passes down to Hot Dog (Scar).
Either this magazine, or another copy of the same issue, is later in the possession of Eammon Pike on the Demetrius (The Ties That Bind).
