Well that helps - in a negative way!

So, all I have to go on my is the initials GC and the date the chips were ordered, October, 1927.

Assuming the C stands for Club, if there was a "G" Club that opened in late 1927 (roaring twenties), we might have something. I wonder, maybe it is the mysterious Garden Club.

I'll leave it on my site as the Garden Club only because I can't disprove what I've been told
