This is an urban letterbox, located in the Valley Cemetery in
Manchester, NH.

First you have to find the gravesite of Electa Sanborn. Here is a
clue: she and her husband are on the side of a hill.

Directly behind their tombstone, in the corner of the stone wall, is
the "Tombstone" letterbox. It is a minature box. Please be discreet
and read the waiver!

Thanks,
Amanda from Seattle
