US 1969 6c Apollo 8 Moon Orbit Stamp

The stamp that brought Earthrise to the mailbox. Issued in Houston on May 5, 1969, it reproduces the photograph the Apollo 8 crew took as they orbited the Moon over Christmas 1968, the Earth hanging above the gray lunar horizon. It is the quiet companion to the Moon landing airmail issued four months later: one stamp shows where humans were going, the other shows what they saw looking back. With more than 187 million printed, it is an easy and rewarding addition.
