Ed Ruscha's is not a photographer per se, thus his photography is very conceptual and thematically and stylistically as far away from the works of Vivian Maier as you can possibly imagine (as seen in the background of the picture above).
I have put out "Los Angeles Apartments" and "Photographer". These books will certainly not be appreciated by everyone, but if you are open minded, it is definitely worthwhile giving these books a look for a view into how a very interesting and important artist uses photography. Most of the photographs are done several decades ago, but remains fresh.
You'll probably need a hand drip with these books :)
