I spotted a dozen or more of these painted aerosol cans last summer in a tree that's growing inside the spiral ramp that leads from I394 near Penn Avenue in Minneapolis to the bike path below. By the time I got back with a camera, yesterday, only six or seven remained. While the stencils look familiar, I can't place the artist.
Update: It looks like it's by Sweet E. Domestic -- a.k.a. S.E.D. Thanks, Bri!
