Auster earned an art degree in college and then spent a number of years in commercial art, doing surfer-themed t-shirt graphics and other such work. Around 20 years ago, he shifted to painting. His style evolved into broad-brush, sketchy, impressionist (but not of the broken-color variety) painting featuring strong use of color to help create atmosphere. He did a good deal of plein air work, much of it in cities. In recent years he painted many bar and restaurant scenes.
An interesting practice was the titles her assigned to his works. Often they are ironic takes on what he was depicting, as can be seen in the sampling below.
Auster's urban scenes often made use of strong value contrasts. This also has some contra-jour.
A rainy winter day in California (rains can get very heavy there at times).
The background image is George Bellows' Dempsey and Firpo (1924) located at the Whitney Museum of American Art. So I wonder if this is a scene from an actual bar.
The background painting is Old King Cole by Maxfield Parrish, located in the King Cole Bar in New York's St. Regis Hotel.
The background image is Renoir's Luncheon of the Boating Party that is housed in the Phillips Collection in Washington D.C. Perhaps a reproduction or copy is in a bar unbeknownst to me.
