There are very few Denny Denfield derriere photos in my collection, and I have posted nearly all of them in the past year.  (As an amateur, Denfield didn't have to worry about arrest, so perhaps he felt less inhibited than his more commercial peers.)  So you Bum Brigade members will have to make do with this unconventional take on the motif.  I find it attractive, and the shoes at the side add interest.
