Side view, 23 Highland Drive (W.M. Chappell House), Queen Anne Hill, Seattle, Washington. Queen Anne Historical Society page about this house. It is somewhat ambiguous whether the curved street here is on Queen Anne Boulevard. The ordinance designating the boulevard would seem to include this block, but the signs indicating the boulevard begin just east of here (to the left) where N. Bigelow branches off of Prospect at a 45° angle.
