As a hobby photographer, intellectual property attorney Greg Revera never thought his snapshot of a full moon would one day have the potential to be viewed by millions, affixed to the right-hand corner of mail sent across the country.

But a photo he took in 2010, which shows the glowing orb’s surface and craters contrasted against the pitch black of space, will be featured on a U.S. Postal Service Forever Stamp to commemorate the 50th anniversary of the Apollo 11 moon landing, which is July 20.
