Well, ER, W Adams does intersect with Orange
Drive.... The Orange you are thinking of was Orange Street, which, yes, did become the downtown extension of Wilshire (in 1924).
I believe what it says on the back is "West Adams-Orange Br[anch] #360--this was at 5133 W Adams, nwc Orange, which seems to be gone.... Looks like before it was demo'ed it was the House of Carpets (late '50s), then a branch of Golden State Life Insurance ('60s--its "West Los Angeles Office").
