Art and Soul, 200 block Pennsylvania Avenue S.E. Washington, DC.
A nice way to use the 3 feet of public space that DC stores are allowed to use in front of their shops without additional permits (unless they are selling), by using an atypical promotional "sign." These types of mannekins aren't cheap, but could be fabricated by a local high school vocational arts program. (Many Main Street programs work with local vocational programs to fabricate the devices used to affix banners to lightpoles.)
