Butterfly Blotter Paper Archival Print by John Van HamersveldButterfly Blotter Paper Limited Edition Archival Pigment Print Art on Perforated Blotter Paper by John Van Hamersveld pop culture LSD artwork. "The butterfly comes from the West Coast Pop Art Experimental Band in 1968. It was a black and white drawing. Then in 2013, I did another version of it, because I was going to make a poster of it. Then it went on to become a mural and onto the blotter we see today." John Van Hamersveld
