I got these 2 chips in and looked them up in TGT2. I found:
CAM from the Old Heidelberg Club in St. Claire, Mich 1936
HSD from Harold Brown's Club in Ecorse Mich 1936
Are these attributions correct? Do we know any more about the clubs? Since they turned out to be Michigan, I don't need them for my collection. I have the one 5.00 HSD, a $1.00 pink and a $10.00 black CAM. Drop me an email if you can use them.
Thanks, steve
