Satchmo’s Stamp of Approval

They called him “Satchmo,” “Dippermouth,” and “Pops” — but by any name, Louis Armstrong was jazz personified. With a smile as bright as his trumpet’s tone, he brought a new sound to the world, redefining the art of improvisation and making jazz a household favorite.

As we celebrate Jazz Appreciation Month, Armstrong’s music continues to swing, and his stamp remains a fitting tribute to a true jazz pioneer.

Born in New Orleans in 1901, Armstrong started playing the cornet at the Waifs’ Home for Boys. From riverboat bands to the jazz scenes of Chicago and New York, he went on to reshape music with dazzling solos and signature scat singing. Whether belting out “Hello, Dolly!” or “What a Wonderful World,” Armstrong’s voice and trumpet were unmistakable.

Decades after first captivating audiences, Armstrong was honored with a stamp in the Legends of American Music series. Issued on September 1, 1995, the stamp, illustrated by Dean Mitchell, captures Armstrong in his element — cornet in hand, clutching his signature white handkerchief. The dedication ceremony took place in his hometown at Louis Armstrong Park, with Wynton Marsalis leading the tribute.

Just weeks later, on September 16, 1995, Armstrong’s stamp was reissued as part of the Jazz Musicians stamp pane. This collection, also part of the Legends of American Music series, celebrated such other jazz greats as Coleman Hawkins, Jelly Roll Morton, Charlie Parker, and John Coltrane — an all-star ensemble of innovators who, like Armstrong, shaped the genre.

Collectors take note: A tiny microprinted “ARMSTRONG” hides just below his wrist on the stamp — an Easter egg for those who look closely.
