I used to own a ton of He-Man toys when I was growing up, I honestly think I had every one of them including the Castle of Greyskull playset. I'd spend hours upon hours playing with the toys setting up elaborate action sequences. Damn, those were the days!
Planet-Pulp is currently holding an art show that pays tribute to the greatness of He-Man and the Masters of the Universe. Here's a brilliant illustration for the show from artist Matt Luxich that features three boys playing with Masters of the Universe toys and letting their imaginations go wild. The piece is called "Masters of Imagination", and I love the concept and how it turned out!
