Speaking of CC monograms, I found this match recently from College Club in Seattle. TGT lists a College Club with CC markings on its chips but no other identification. Steve Goodrich's Washington book does list the College Club of Seattle as having gaming.

Maybe this will help identifiy the source of the chips referenced in TGT. Did they look like the match monogram, Allan? Still no street address in Seattle, though.

I have an extra of this 1940's bobtailed cover for trade, or will sell for $5 delivered.
