If it wasn't for the signature on this intense portrait study, I never would have guessed it was by Gustav Klimt — an early experimentation of his, quite modern in an illustrative way. It looks rather like a 1960s' Time magazine cover illustration of a famous conductor or architect, maybe by Barron Storey, or Bernie Fuchs or Bob Peak — with its concentrated coloration and characterization.
