Thank you for all that information Robert.

I corrected the spelling to Monaco and updated the listing.

I agree that it probably was not a poker card room, but I'm not sure how best to list it. When I look through old newspaper articles, I see mentions of skill games being offered in the Ocean Park area called "pokerino" and the "hot-cha chip game". I have no idea if any of these games involved cards.

The only real options on the ChipGuide are Casino, Card Room, Illegal, or Non-Casino (other). Club Monaco and other similar clubs were not illegal, as the operators claimed the skill part of the games made them legal according to California law, and they were largely left alone by law enforcement. They were also not really Casinos, in how we commonly understand that term. Non-Casino (other) does not seem to capture the gambling part. I'm open to suggestions.

By the way, Max Votolato in his book "Gardena Poker Clubs: A High Stakes History" (2017), claims that Ernie Prim got the idea of opening the first legal card room in Gardena after visiting the Ocean Park area in the 1930s, and seeing skill games called "skillo" and "tango" being legally played there. In the 1930s, Skillo was offered at his Embassy Palace, before draw poker.

Also, do you own that "Club Monaco, Ocean Park" image? If so, can I upload it to the ChipGuide listing?
