Deletion of Barry Masteller

Comment: I have confirmed three collections, so he meets . I added a couple sources. They are hard to come by, as most seem to be mid 90s or earlier; many articles were published -- according to the https://web.archive.org/web/20201018023521/https://barrymasteller.com/cv_bio.htm CV page on his web site. Additionally, much of the article text was a direct match with the same CV page, and seeing as it was all unsourced, I removed it and the previous versions can be rev-delled by a friendly admin if they happen to read this (i.e. https://en.wikipedia.org/w/index.php?title=Barry_Masteller&direction=next&oldid=984087588|everything before this version appears to be copyvio). Pinging {{ping|Coolabahapple}} and {{u|Dom Kaos}} to see what they think of the collections

Comment: article states that Mastellar works are held by Crocker Art Museum, San Jose Museum of Art, Monterey Museum of Art, Santa Cruz Museum of Art and History, Triton Museum of Art, that would mean he meets  but only if this can be confirmed (article has no |references showing this, and i've been unable to find any), so this is a '''delete
