Hey now! I thought Bob Ross was the shiz back in the day (granted I was a literal kid at the time, but damn it was cool! :) )

IIRC, he spent most of his time working in the PBS arena, doing the '70s artwork schtick. 

 

Now the guy I want to beat to death with a can of paint (err, right after I shake his hand for beong so damned clever about it) is the guy who invented the velvet paintings - especially the one who did those Mexican kids with the really big eyes that spooked the unholy shit out me as a little kid. >:(
