I've got them down as having been used at Bertulucci's (not sure of the spelling since I don't have my material with me right now) in Santa Cruz, California. The guy auctioning them mentions them as having been used in a California club too, but after the LA tournaments. I'd agree they are more LA than CA but if you're a California collector it's the kind of thing you'd probably pick up since there is also a CA connection.
