Hard to find Kozik 1987 Ministry poster. stained and other damage, but basically intact. Actually, the stain adds to the visual effect (ha-ha). A very powerful image!
ITOYA STAINED = it got wet while in an archival art portfolio made by Itoya. The black backing sheets bled onto the art leaving dark purple stains. If the picture doesn't show much stain, then the back is probably worse. The stain can be reduced by soaking in water and rinsing several times, but this is risky, some papers may not survive at all. I can't bear to put them in the recycling bin, so here they are (search under ITOYA STAINED)
