Cinderella stamp

Sponsorship the way you would do it
A cinderella stamp is a postage stamp like label which may or may not be issued by a post office.

Cinderella stamp collecting is similar to stamp collecting.

The first cinderella stamps were revenue stamps issued by national, state or local governments.

A significant number of cinderella stamps issued in the 1910s and 1920s were advertising poster stamps.

One of the most notable creators of cinderella stamps was A. C. Roessler, a stamp dealer, who created many visually attractive cinderellas during the 1930s
