As a longtime collector, I enjoyed David Lander’s column about marbles (“History Now: The Buyable Past,” October 2003). Anyone interested in these engaging artifacts should be aware of two great exhibits near where I live. At the Moon Marble Company, in Bonner Springs, Kansas, Bruce Breslow and his partner, Lynda Sproules, make exquisite marbles with century-old techniques (some of them sell for as much as $350). Not so far away the Toy and Miniature Museum has just put on permanent display a marble collection donated by Cathy and Larry Svacine, which, with over a million examples, is the most complete in the world.
