Happy Presidents’ Day.
This ensemble of US presidents on postage stamps issued by the U.S. Postal Service is from my modest collection of US stamps.
President George Washington appeared on one of the very first U.S. postage stamps issued in 1847 (a 10-cent stamp). He subsequently appeared on over 300 different U.S. postage stamps— more than any other individual in U.S. postal history, and more often than all other U.S. presidents combined.
(The U.S. Postal Service has not issued a stamp yet of President Obama— nor of Presidents Bill Clinton, George W. Bush, Donald Trump, and Joe Biden. A key USPS policy rule is that a person must be deceased before their likeness can appear on a stamp, similar to the rule that is in place for coins and banknotes at the US Mint.)
