Mowry Baden, Night is for Sleeping, Day is for Resting, 1997.

The other day my friend KB enlightened me to the fact that this sign (which is located about 6 blocks from my apartment at the foot of Beacon Hill Park) is the work of Canadian artist Mowry Baden - and not, as I had assumed, an inadvertantly brilliant advertisement for the resting home behind it.
I don't really know much about Baden's work (other than the fact that I really love this sign) but there is a good review of his recent show at Diaz Contemporary here, written by Simpleposie's Jennifer McMackon.
