Hi I just joined this discussion. I have a black light silkscreen poster, (7 colors, aprox 28 X 22 inches) of Jimi Hendrix by the artist Ron Walotsky. I purchased this in a shop in the late 60's, I think 1968/69. I've been trying to find out about Ron's work from this period and also trying to place a value on it for insurance purposes. But all the information I find deals with his fantasy art. I have been told that during the late 60's he did work with rock groups, (Jim Morrison, etc). Does anyone have any more information?
