On April 22, 1990, the world joined together in an effort to make the population of the Earth aware of the environmental dangers we face. As their contribution to the cause represented by Earth Day 1990, Paul Chadwick, and Dark Horse Comics have joined together to create a unique comic experience-Concrete Celebrates Earth Day. A 32 page full color comic, Concrete Celebrates Earth Day contains new stories featuring Chadwick's Harvey and Eisner award-winning character Concrete, plus stories by artists Moebius and Charles Vess, all designed to heighten our awareness of the environmental problems that threaten us all. It is a comics experience that is not to be missed.
