Mostly unpublished, painted for original-art collectors, these ink-line-and-watercolor paintings of Concrete, Larry, Maureen, and Tripod appear now in this collectible card set. Most tell a story in themselves, but also appearing are scenes from Concrete's origin, and a 20-card subset retelling Concrete: Think Like a Mountain. Commentary from Chadwick and rare line art, some unpublished, appears on the backs. An entire gallery of little-seen art from one of comics' most acclaimed creators.
