This one has caused some speculation among illegal collectors:
MSC chips shipped to the famous Muskogee Social Club, 233 W 72nd St, NY NY, 11/1930.
However, a batch was also sent to Jake Katleman, famed casino owner, to a Los Angeles address in 1938.
Any more ideas on this one out there? I have a couple extra fs/ft. Just drop me an email if you need one. Steve
