Klondike Cafe. John Bohnenberger. I had the privilege of meeting this gentleman before his death and helping organize his last retrospective show in San Gabriel, CA. He worked in the U.S. Postal service most of his life but was happy to paint wonderful watercolors, often using both sides of the paper. The last of the great California watercolorists of the 50's, an era of very distinct, angular and clear-eyed art that permeated the culture -mostly through cartoon backgrounds .
