Today I came across a couple of links showing photos of Mr. Taylor and a customer going through an initial appointment.
Another blogger met with the Taylors earlier this year and took photos of the couple and finished garments lined up on a rack (scroll to the February 1, 2006 entry).
On The Fedora Lounge, there are additional photos in a recent discussion thread, this time of an initial measurement with Mr. Taylor's head cutter/tailor, whose name I believe is Sam.
More photos appear in this AskAndy thread, including one that features a Jack Taylor suit with a more set-in shoulder.
Update: Taylor in a Men's Style video interview.
