[1] The fresco features a giant barefoot and bare-chested male mailman flying over a town scene whilst holding a winged letter.

[1][2] This was chosen as Melrose Park was one of the first airmail facilities used by the United States Post Service and the fresco was painted to commemorate it.

[2] When the post office closed, it was renovated to become the public library, during which time the fresco was lost and presumed destroyed.

[3] The mural was rediscovered in 2007 following a man named Richard Grunt investigating Johnson's work after remembering seeing Airmail at the post office when he was a child.

After a six-month restoration, it was unveiled at Melrose Park Historical Center before being returned to the library for permanent display.
