There is only a little information about this drawing:

• It is a detailed pen-and-ink drawing of a wood-framed bay window
• The sheet dimensions are about 20 inches by 27 inches
• It was designed for a Monsieur Cohier
• The house (presumably it was a house) was projected for Dourdan, a suburb of Paris in the Seine-et-Oise department

Unfortunately, the architect is unidentified, neither is it dated—except for the Art Nouveau characteristics of the lettering that put it about 1905-1910. Things like this come along infrequently, so I’m inclined to make as much of them as possible. How do you suppose this can become part of the Agincourt narrative?
