3/2/2015: According to Eric Zetterquist, Kenneth Barr was an elderly and very private English collector who lived close to London, but not in London. Barr started collecting in the early 1960s/1970s; Zetterquist met him in the early 1990s. Barr has since died, but Zetterquist is does not know when.
