Mercer Island by Air
In 1937, the federal Works Progress Administration, along with King County, undertook a project to find and classify all lands in King County. This included Mercer Island. You've probably heard of the "1937 Tax Photo" for a given property in King County--this is the survey that created it. To assist photographers in finding properties, aerial photos of the entire county were taken, all 2,151 square miles. Below you can now access those aerial views of Mercer Island to actually see it as it appeared in 1937.
