Continuing with the theme of the Four Horsemen of the Apocalypse, is Virus Iris and Plague Paula representing Pestilence. The 24-card Apocalypse subset of Adam-Geddon has 10 cards dedicated to the Four Horsemen theme. This isn't Virus Iris's first appearance as a GPK, however.
Virus Iris and Sicky Vicky were original members GPK in its 1st Series. Shown below is the 2013 Chrome reprints for OS1 #21a/b. Don't underestimate this Chrome reprint version of the original Series 1 classic GPK set. The scans below do not do these cards justice. The gold background shimmers along with it colorful picture. Although I originally purchased this set as cheaper alternative to a nearly unaffordable set, I'm thinking about getting the 2nd Series Chrome set to go right along with it. The GPK Chrome sets just seem to further immortalize these original classics like no other.
