1960s Hippie Era Psychedelic Artwork from Vancouver with Iron Butterfly & Led Zeppelin imagery.

I don't think I previously posted this period artwork I got a couple years ago. It is from the 1960's Hippie Era with rock references to Iron Butterfly and Led Zeppelin - however I believe it is Gang Related (online research shows Clark Park in the 60s wasn't a nice place) but still a very psychedelic original painting from Vancouver BC. The incongruity of the Peace & Love on the front and the Satan "worship" pencil "art" on the back is startling. It is possible the artist used an old board to create his vision, perhaps drug art... or vice versa... or the obvious is the reality. A period time capsule displayed in the folk art of the time.
