MINI ZONK has a cool pattern that seems to change as the light changes!
A Moire effect that is quite trippy! Look at this ,gif to show you the variations!

Antique 60'a/70's era Silk Screen Print Black Light Poster
Marked in corner "SCREENPRINT U.S.A."
Size:12 inches x 12 inches

thick stock
Condition: Very Good/Good - may show some signs of age at edges
Colors are bright - and really show up under a BLACK LIGHT!
I do not have the date on this one, though it is late 60's/early 70's from SCREENPRINT U.S.A.

Rare VINTAGE psychedelic poster art - authentic, antique, collectable, unique!
Due to the nature of the silk screen process at the time, each one is a little different, and there is variation in the edge of the print.
I have just a few of these - when they are gone they are gone!
