Two generic Presidents by the one artist listed in BOTH the Guiness Book of World Records AND Ripley's Believe it or Not. That would be the world's fastest artist, Morris Katz (1931-) I used to see him walk around New York City in the early 1980's. He had a television show of his own at the time, "The Instant Art Show" in which he would churn through canvas after canvas while appraisers watched. According to the artist's website, Mr. Katz is still available for Publicity Stunts, Corporate Events and more. Whatever the price, it is a steal. As his website asks "how many of you can say you have seen someone paint thirty-six 8x10 inch paintings in one hour?" The link here shows more of the Morris Katz Presidential series. Seldom a day goes by without a Katz being listed on Ebay. The more common (and by that I mean, THOUSANDS AND THOUSANDS and THOUSANDS of more common) are usually palette knife works you can't avoid at flea markets. God willing, Mr. Katz is working on his Obama.
