This flier is a handmade screenprint made with the Gocco Printer.

 

The Gocco Printer is a Japanese color screenprinting system developed in 1977 by Noboru Hayama. Resembling a toy, the compact and completely self-contained printer is clean, quick and easy to use. The system works using flash bulbs, a carbon-based image or photocopy and an emulsion-coated screen.
