Engine 494 was pulled at Magnolia Editions in Oakland, CA on a flatbed transfer press. Each of the 3 runs was drawn separately by Gus Heinze on translucent mylar. The drawings were transferred to plates via contact printing. The prints were pulled individually, one color run at a time. After a proofing session, where various color changes were tried, the artist selected a right to print which was used as the standard for the edition. The artist continued to make changes and refinements and added more runs to the print during the editioning.
