I would have no issues with sponsored stamps. If companies played it right, they could feature retro logos as an exploration of the history of their company or the art of marketing. Heck, why not offer a nickle discount for a sponsored stamp....
NASCAR sponsors? NFL helmets? New fall TV shows? New movie releases? I don’t care.
Indeed. The post office needs money and this would be a way to raise some cash.
But no matter what the post office is going to have to find some way to deliver mail without tons of paper except for those willing to pay the full cost of its delivery.
