The first, and only, book dedicated to Mark Grotjahn's rarely seen colorful cast bronze sculptures. Over 100 sculptures illustrated. Mark Grotjahn's Mask sculptures are deceptive. Cast in bronze from spontaneous cardboard assemblages that he has been working on privately for over a decade, they record all the nuances of the original found material with its corrugations, dents, tears, and creases. The bronzes are vigorously painted, often with the fingers, in a riotous spectrum of color. The Mask sculptures recall the simple cardboard-box constructions typical of early classroom activity—emulated so charmingly by Pablo Picasso for his own children during the idyllic Mediterranean years.
