Yeh's amusing work was sold Tuesday alongside other items at an auction aimed at raising money for the Larger than Life association, which works to improve the quality of life and wellbeing of children with cancer and their families, regardless of religion, race or gender.
Phil Yeh, 57, founded his studio and personal publishing company in Los Angeles in 1970, when he was only 16.
His work has been published in American newspapers over the years, and in 1977 he wrote, illustrated and published one of the first modern American graphic novels, "Even Cazco Gets the Blues," which featured introductions by MAD magazine cartoonist Sergio Aragones and late Golden Age comic book creator Don Rico.
Yeh has published more than 70 books so far, and in 1985 he founded the Cartoonists Across America & The World organization, which uses humor to encourage reading, creativity and peace.
His band of artists has painted more than 1,700 murals in 49 states in the United States as well as more than a dozen other countries – from China to Hungary.
Every year, Yeh lectures in front of more than 100,000 students in schools, libraries and conferences across the world.
