Being in the retail industry I have an interest in the many marketing methods used - especially when they involve stamps.
Trading stamps have been around for over a century. No-one seems to know who did them first but the largest and most successful trading stamp company was Sperry & Hutchinson who started in the United States in 1896.
This thread has been set up for collectors to record their American Trading Stamps.
I have also set up threads for trading stamps from Australia and Britain.
