I agree with everything you say. I figured the "Ninety Club" would be more common but I'm not seeing any. So many clubs are named after the address but I guess most street address are longer.

Maybe I'll poke around a little more. That hot stamp does seem to be purposefully designed, so maybe there is advertising similar.

Only in the last year have I started getting more into California chips. I hesitated for so long because its difficult to know what is illegal and legal sometimes and I'm just not interested in legal card rooms.
