Wolo liked doing murals and he painted several in and around San Francisco. Few are left. He painted a series of "cocktail characters" on a big mural in the New Pisa restaurant in the city of San Francisco around 1971. The mural stood for many years, than the restaurant was sold and refurbished. Mr. John Burton has sections of the old mural and was kind enough to photograph several of the paintings and send them to me. Take a look.
