I was a big fan of "He-Man and the Master's of the Universe" when I was a kid. That being said, I purchased all four volumes of the original series on DVD. Each volume came with two "collector's edition" postcards, each with an original print from a different artist. There are supposedly sixteen cards in the set. My question is, where can I find the remaining eight cards? Am I going to have to purchase the "Best of" DVD as well as all the She-Ra sets to get the remaining cards? Any info on this would be most appreciated! Thanks!
