Along the lines of Dear Doctor correspondence from drug manufacturers marketing products to physicians...

I came across a few First Day Covers which were used to advertise medications. The attempt to connect the topic of the stamps to the medication being advertised seems like a stretch but the drug manufacturer put forth their best effort.

As unusual as it sounds both products remain in use today in the field of medicine.

All of us who live in the US or NZ, the only countries on earth that permit the practice.
