ERIKA SCHULTZ / THE SEATTLE TIMES
David Youngblood of Oso, Snohomish County, looks up at "Shared Clothesline," part of Frye Art Museum's "Surveyor" retrospective show on Buster Simpson. The Seattle artist hung the artwork 35 years ago in Post Alley between a condo and a fixed-income residence. Simpson, a trailblazer in urban environmentalism, lived and worked out of a studio below the fixed-income residence in 1978. "Clothesline" will be displayed until Oct. 13. More of Simpson's work can be seen at the Frye.
