These are 8 duplicate covers that I've had for a number of years. Notice that the California Bell called itself a Casino on one of these. Also, the three Rainbow Club covers all advertise the Primadonna Club in Reno on inside printing. Three front strikers and five back strikers. The F.S. covers are 40+ years old and the back strikers more recent but still 10 years old or so. All covers have inside printing (not blank inside).

I will send all 8 to someone with a USA address and who sends me $12.
