GaylordWilshire you are amazing! the find on the location of el centenario cafe is brilliant. On page 131 of Gernot Kuehn excellent 1978 book, "Views of Los Angeles" he has the photo of the el centenario with a caption that reads;
The El Centenario Cafe, 1920's
A corner of Old Los Angeles that no longer exists today. Does anybody know where it is?
now we do!
the image you posted showing the hall of justice would be at the NW corner of Spring and Aliso today.
excellent work!
