The Sun Cleaners dry cleaning sign at Woodlawn Avenue and N 45th Street in Wallingford

I've always liked this picture. This is a picture of a dry cleaning sign located at the intersection of Woodlawn Avenue North and North 45th Street in Seattle's Wallingford neighborhood.

When I took this picture, the Woodlawn Ave N street sign was over the words "DRY CLEANING" which were displayed on the sign, above "DRIVE IN".

I really like this sign, and I wonder how old it is.
