Electric Works here in SF releases this great blacklight Mars-1 print.

This limited edition poster brings back the best of underground poster-making from 1970s. The rich velvety black is just that: virtually the whole print is covered in black flocking. Underneath that is a layer of UV-reactive fluorescent day-glo inks. Each print is signed by MARS-1. Tack it up in your dorm room, frame it for your study—this print is guaranteed to elevate the look of any wall it's hung on.

Each 32" x 25" poster is signed by the artist and due to the hand printing of the silkscreen each one varies just a little from the other making every one unique.

This is a limited-edition signed and numbered blacklight poster. The color background was applied with a process called "Split Fountain" in which all 5 colors are put on the screen and mixed into the gradient in one pull as the squeegee goes across the screen. Each pull mixes the inks a little differently so each print is unique. The fluorescent inks are UV reactive so the poster has one look in the daylight and totally different colors under blacklight.
