Famed Spanish painter (7)
I believe the answer is:
picasso
(Other definitions for picasso that I've seen before include "Prominent cubist" , "Pablo . . . . . . ., great Spanish artist of 20th century" , "20th century painter" , "Spanish artist who emigrated to France, d. 1973" , "Pablo . . . . . . ., extraordinary 20th century artist" .)
