One of the maps sold at Bonhams for $62,500 in 2012.
An Apollo 12 surface-worn backpack strap carries an identical starting bid of $2,500.
Astronaut Charles Conrad wore the strap during his Moonwalk on the Sea of Storms in 1969.
It's accompanied by a letter of provenance from Conrad that reads: "This strap helped support the 'PLSS' Backpack on my spacesuit during my historic four-hour moonwalks, becoming directly exposed to the lunar environment as a result!
"We were allowed to keep, and return, a few personal mementos from the Moon as keepsakes, and I included these disposable straps among mine.
"After this strap's release from quarantine, and return to me by NASA, it remained a treasured part of my personal space collection until 1992."
