I checked out the 1978 book on Anhalt from the public library and wanted to tie up some loose ends and make some corrections.
First, Anhalt did erect some Mediterranean-style buildings. The book specifically notes that El Monterey was not among them, however.
Second, the book cites “thirty” buildings, but does not provide a detailed census.
Third, my citation of the Canal Market to the west of Montlake is not supported in the book. Since there’s no comprehensive list of buildings, I could still be right, but the book doesn’t mention it in the section on Anhalt’s early commercial architecture.
Fourth, I attributed the design elements to a single pattern book. Apartments by Anhalt cites several by name.
