Roosevelt's Stamp Collection

U.S. President Franklin Delano Roosevelt started collecting stamps as a child and continued with the hobby throughout his life.

During his years in the White House (1933-1945), he was greatly involved in the design of about 200 stamps that were issued, according to the Smithsonian Institution.

There's a great video, The Stamp Collector in Chief, that you can watch online. It's an interesting story.
