Chicago, IL: Daniel Mellis, 2010. Limited Edition. Original Wraps. "Ars Combinatoria is an exploration of the graphic possibilities of a single piece of wood type—a thirty pica Clarendon R—and a restricted set of operations—positive and negative auto-pressure printing with only one inked impression. This technique enables the top of the wood type to interact with the bottom and itself. " Mellis became intrigued with how many different ways a single block could be printed and this work is the result of his exploration. Each sheet bears a pencil notation indicating the order of strikes and which side(s) were inked. There is also a small booklet—printed in three color offset lithography—explaining the process. A simple and brilliant exercise. Fine. Item #7573 Bright and unmarred. Beige drop-spine case, loose plates, small pamphlet slotted into the bottom. Small 8vo. np. Illus. (b/w plates). Numbered limited edition, this being __ of 30 copies.
