TCT only states:

Alcazar Card Room
842 4th Ave
San Diego, CA
Opened 1952, Closed Yes.

Allan normally lists the mold (in this case, crest & seal) if known. Also, the chip is a USPC chip definitely pre 1940 NOT 1952. Lastly, TGT does not mention Jack Shivel.

The Alcazar chips are not San Diego if TGT is the attribution source.

Miami, Chicago or Cleveland are left. San Diego is out.
