National Defense Stamps

This series of postage stamps, temporarily replacing the regular issues, was provided to create a general consciousness of the existing threat to our security and focus attention upon the necessity for developing an adequate national defense.

The dimensions of these stamps are 0.75 by 0.87 inch, arranged vertically. They are printed in the regulation colors for these denominations by the rotary process and issued in sheets of 100. The stamps were first placed on sale in the Washington, D.C., post office on October 16, 1940.
