The Wabasha Street Caves provide the perfect noir background for host Mark L. Walberg and appraiser Simeon Lipman to discuss the history and collecting of flashlights. Highlights include an 1863 Ulysses S. Grant letter; a circa 1950 Charles Shulz Li'l Folks original cartoon; and two paintings - one by Victor Higgins, the other by Spencer - purchased together for $5, but valued at $75,100-$75,200.
