Porte-timbre

A porte-timbre is a small framed ad, gummed, with a postage stamp affixed. In France, they came in advertising booklets, sold at a discount from the postage stamps included. They were later distributed free of charge.

Not only were they used for advertising, including philatelic, but also for other types of publicity or political causes. Other countries also used these.
