The recent DWR newsletter features a contest to identify the designer or location of a 1952 house by an "influential but relatively obscure" architect. The first 20 responses to either name the architect or the location of the residence will receive a book devoted to the architect in question.
The images are worth a peek even if the contest doesn't appeal to you.
