Hmmmm....assuming it's not from Havana, Cuba(i shouldnt assume) then perhaps one of the illegal clubs called the Jockey Club??

That sure doesnt narrow it down very much since there were Jockey Clubs in :

Galveston, TX
Newport, KY
Montrerey, CA
Billings, MT
Atlantic City, NJ
Paris, France
San Antonio, TX

Ok...anybody have any ideas?
I'm also still looking for id's for the other dice in the scan.
