Litto's Hubcap Ranch in Pope Valley, Napa County, California. A California Landmark plaque reads: This is one of California's exceptional Twentieth Century folk art environments. Over a period of 30 years, Emanuele 'Litto' Damonte (1892-1985), with the help of his neighbors, collected more than 2,000 hubcaps. All around the hubcap ranch are constructions and arrangements of hubcaps, bottles and pulltops, which proclaim that Litto, the Pope Valley Hubcap King, was here.
