Marcel Pauker (1896 - 1938) - ein Verfemter

Fair use Rationale
This qualifies as fair use because:
 * It is used to illustrate the object in question
 * There is no free equivalent available/could be created that would adequately give the same information (he died in 1938, so it is impossible to take a picture of him now; this is also a historical photo)
