"Stamp collecting dispels boredom, enlarges our vision, broadens our knowledge, makes us better citizens and, in innumerable ways, enriches our lives."

So said President Franklin Delano Roosevelt, whose passion for stamps began in childhood and continued throughout his presidency.

Roosevelt reportedly dedicated half-an-hour to philately every night during his time in the White House, apparently as a "stress buster", and stamps were incorporated into much of his governance.

The President played a critical role in the creation, design and promotion of some 200 stamps released during his time in office (1933-1945).

On a number of occasions, Roosevelt even took the pencil from the stamp artist and designed them himself, such was his passion and extensive knowledge.

Roosevelt's stamps were often used to help sell his policies, reinforce his role against critics and reach out to voters.
