LOWER ALSACE TWP., Pa. -

More than 3,000 items from David Letterman's two late-night talk shows are going up for bid in a series of online auctions being conducted by a Berks County-based company.

The trove of props and costumes being sold include clothing worn by the now-retired host and his guests, costumes worn in the shows' comedy skits, and props from bits done over the years.

"If you include 'Late Night With David Letterman' and 'The Late Show With David Letterman,' about 5,000 shows were produced over the course of 31 years," said Bill Howze, of The Renaissance Auction Group, the Lower Alsace Township-based firm conducting the auction. "Thousands of props, costumes and accessories were used during that period, and they are now being sold at auction."

The series of auctions is titled "Last Late Show Dates with Dave," and will be held Monday through Friday, September 19-23, from 7:30 p.m. until 9 p.m.

Lots can be viewed on the auction group's website and bid on now through the closing of each auction. They can also be previewed in person September 17 and 18 at Beyond Costumes Inc. in Yonkers, New York, The firm's owner, Yon Zweibon, acquired the items last summer after being contacted by a designer in the show's waning days.

Letterman stepped down as host of the "Late Show" in May 2015, turning the reigns over to comedian Stephen Colbert.

The September 19 auction will include costumes, clothing and props worn by Letterman, his flamboyant band leader, Paul Shaffer, and other cast members, and items used in skits by Bill Murray, Joaquin Phoenix and Martin Short, among others, as well as memorabilia from "Star Wars."

Items going up for bid on September 20 include military-themed clothes, uniforms and props, Letterman- and Shaffer-worn suits, and African-influenced clothing.

The September 21 auction will feature additional U.S. military-themed items, a large group of chefs' hats and jackets, a Letterman-worn Brooks Brothers shirt, and masks used in various themed skits.

September 22's session will feature baseball and basketball uniforms and equipment, a Madonna Super Bowl costume, a U.S. Masters green sports coat, and a distressed Boston Red Sox baseball jersey.

The final auction on September 23 will include Hawaiian print shirts worn by Letterman, a variety of men's hats, Speedo swimsuits, Everlast boxing gear, and women's suits used in Hillary Clinton skits.
