This piece of unsolicited mail arrived today at the Massachusetts Historical Society and was spotted by my friend and colleague Jeremy Dibbell.

The address reads:
Massachusetts Historical Society
1154 Boylston St. Boston MA 02215
The only problem is that the MHS was founded in 1791 and our dear departed Reverend Belknap -- now being solicited by Google -- died shortly thereafter in 1798.
