Such great photos lately!
Last night I watched "Ask the Dust" starring Colin Farrell and Salma Hayek. I actually liked it. Yeah, it was actually filmed in South Africa, yeah, the production designer should've recreated the 3rd Street tunnel instead of the 2nd Street tunnel; but I liked the movie (if anything, I had a problem with the style of street lamps that were used-- totally incorrect). Almost makes me wanna read the actual John Fante novel it's based on. I liked that the film tried to accurately portray the LA of the early 1930s; that it was still a very transient place, with most residents having come from some place else, either to escape from something, or to accomplish something; either way, they came to LA to reinvent themselves, and the city of LA was reinventing itself along with these people (and the city still continues to reinvent itself).
But anyway, there's a part in the film that deals with Adohr Farms milk, which I thought was a very southern California thing, like Alta Dena Dairy. So I looked it up...
Not sure if this photo has already been posted, but there's an Adohr sign on one of the buildings; this is Broadway some time in the 1920s:

1951; here an Adohr milk man had an accident.

1957; the caption to this photo is "Cherie Leveque, 7-year-old daughter of Rene Leveque of Van Nuys, takes safety pledge from her father in Southern California Milk Distributor's school children's safety campaign. Leveque, milk routeman, along with other men who deliver milk have offered their assistance in providing safety for children on streets."
