Poster stamps of the PPIE
Panama Pacific International Exposition - San Francisco, 1915

INTRODUCTION What was the PPIE? What are poster stamps? PPIE Poster stamps for:  -  Official publicity  -  General souvenirs  -  Exhibitor promotion  -  Local promotion  -  Foreign  -  Awards  -  Railroads  -  Events  -  Other

OTHER These are stamps that don't fit nicely into any other category. As far as I can tell, none of these entities had PPIE exhibits. They seem to be simply product ads exploiting the event.
