In the late 1980s and 1990s it was common for charities to solicit donations using direct mail campaigns that included pre-stamped return envelopes. The transportation coil stamps on the envelope above paid the then current 25-cent first class letter rate. This fund-raising tactic using ‘real’ stamps naturally grabbed my attention. It seemed new, different…and risky!
Looking through an accumulation of collection material recently, I came across a very similar, but much older, use of a ‘real’ stamp (the 2-cent “Empire State Express” issue from the Pan-American Exposition series) to pay for the mailed reply to another solicitation. Interestingly, a transportation stamp was also provided to cover mailing costs in the very early 1900s.
I’d be interested if anyone can provide additional information about this “Profitable Advertising” sample.
