Beacon's Value Village Thrift will throw you a curve when looking for great murals. In addition to a number of great murals on the side of the building, they also have some very cool murals going around the columns in the front walkway. The expanded 4th Ave trolley will pass in front of this once they finish construction of the the rails going to downtown (in progress). Location is 300 N. 4th Ave.
Update (March 11, 2012): These murals were all painted over months or years ago when Goodwill took over the building.
