They are early works by a Hungarian American artist named Istvan Toth (1942-2004).
Not much is known about him except that he lived in the Hollywood Hills and worked from the sixties through the nineties.
But you know me, when I get on the scent...
I believe that he was at one time married to a woman named Brigitte, who I believe is still alive and may be living in Santa Ana.
He may also have a child named Istvan, Istvan Toth apparently being the Hungarian equivalent of John Smith.
Toth worked in stone, bronze and very rarely and early on, in wood.
