A Bag One lithograph. "Bag One was a suite of lithographs by John Lennon that were given to Yoko Ono as a wedding gift in 1969. A series of 14 original lithographs. ... caused quite a controversy as to whether these lithographs were art or pornography, and eventually the art was confiscated by Scotland Yard while on exhibit in London."
