fhammon: There are a couple of shots at the LAPL of Nick's, but nothing very interesting (well, seven years ago there was razor wire strung along the cornice).
I did find the pic at top, though--a great noir-era shot with the P.O. Terminal Annex, a Dodge (or other Chrysler product) business coupe, chop suey, and the Vera Cruz Café at N. Spring and Chavez.
