A painting by Joseph Kleitsch was highlighted on the Antiques Roadshow at New York, Part 2.
I'm going to keep the surprise but the segment is at the end of this episode at 52:55 minutes. Well worth the viewing.
Go to: Antiques Roadshow, New York, Part 2. Don't know how long it will be up at PBS so don't delay.
It's really is worth the viewing.
