My guess was that I always had an idea the cards may have been "reused" or redistributed at a later date (teens) by someone who put the stamp on back and included them within a package deal of small toys/cards/candy etc.. I have seen about a dozen "Toy Town Post Office" cards over last 5 years on eBay, and all have been in VG/EX or lower grade (usually low grade). Its all very interesting.
