8" x 10" collage on cardboard
duchamp thing taken in a fluxus archive book. i will check out for the artist that made the print.

note: because in the actual address of the page, = is besides ( , i can't put the exact link cause the little sad icon screws it all. so i took you the closer i could, then, you just have to click on "synthetic art" in the answers section at the bottom of the page.
