I came across this 1931 shot of the notorious deputy D.A. "handsome Dave" Clark--second from right--strolling southward on Broadway alongside the Hall of Justice (note the union-jack railing at left). In the background is the south portal of the Broadway tunnel. This picture looked familiar to me--I went to my bookcase and found that I'd seen a cropped version of it before in another must-read for L.A. noir fans:
A Bright and Guilty Place by Richard Rayner (Doubleday 2009).
