Provisional stamps are postage issue made for temporary
ad hoc usage to meet demands until regular issues are reintroduced.
Transitional government overprints New states or states in transition have sometimes found it necessary to recirculate stocks of stamps printed by a previous government. Some historical perspective may be gleaned from the study of such stamps: some transitional government overprints blend neatly with their predecessors' designs, while others attempt to totally obscure or even deface the older markings. In several European nations in 1944–45, Nazi occupational stamps were overprinted for the provisional governments, and those which depicted Adolf Hitler were most heavily overprinted, obliterating his face.

Wartime overprints During times of war, many nations have issued
war tax stamps. Before new stamps could be printed, older stamps were frequently overprinted with surcharges or a simple inscription such as "War Tax". In actual combat zones, the replenishment of stamp stocks is generally low on a military's list of priorities. In contested or occupied areas, captured local stamps are often expediently overprinted by the occupying forces. File:Deutsches Reich - Belgien.jpg|
