Here’s a little information about Noah Purifoy from Wiki.
Sometimes when an artist is unknown to me…a bit of background can help. I saw him as an ‘outsider’ artist and was so wrong! Purifoy went to CalArts where he got a BFA in 1956 at the age of 40. He had served in Navy during WWII. He was on the California Arts Council and helped to found the Watts Tower Arts Center! In the 80’s he began a huge project in Joshua Tree that he spent from 1989 to 2004 working on.
