Less than a week after "American Idol" aired a Detroit auditions episode, the city is back on network television Monday night.

"Antiques Roadshow," a popular PBS series, airs a one-hour look at valuable -- and not -- items that metro Detroiters brought to Cobo Center for evaluation last summer.,

The 8 p.m. installment includes a signed 1970 Andy Warhol poster and a century-old Pewabic pottery collection.

A script of "The Wizard of Oz" used on the MGM Studios lot in Culver City, Calif., in 1938-39 by Bert Lahr (the Cowardly Lion) is brought in by his grandson, who found it in a closet. (Spoiler alert: It's appraised at an Insurance value of $150,000, The Detroit News says.) 

The public TV show also: the Motown Museum.

A preview in The News has these details of the June taping, which drew 6,000 people who got tickets in a lottery:

Detroit was the first stop on the show’s 2013 summer tour. According to executive producer Marsha Bemko, almost 29,000 enthusiasts sent requests for the 3,000 pairs of tickets given out at each location.

Stops produce as many as three hour-long shows. . . . Last summer was its first time within city limits.
