This mural by Mark Bode is on the 3200 block of Hollis in the Clawson/Dogtown neighborhood. It may have been painted in one day in 2009, although the portion on the right was added/painted over in 2012 by Deb and may be called Blue Lagoon.
Blog about mural in process.
(Anyone got a picture of the full nymph mural before the new part was added? It's a classic!)
