Antiques Roadshow is off to the races for amazing appraisals at Churchill Downs Racetrack, like a Twin Spires painted roof slate from around 1895, a 1943 Picasso ink-on-paper and 1963 letter, and an art deco brooch. One may be worth up to $200,000!

Trot over to your TV and see which one that is, tonight at 8pm on WGBH 2.
