Gunn Museum in Washington will present a lecture on "Hidden Treasures" June 10 at 1 p.m. as part of the museum's Stoneware Lecture Series.

Guest speaker is Leslie Keno, an expert in the field of antique arts and furniture. He will discuss his adventures in the antiques business and share some of his most memorable discoveries.

Keno and his twin brother, Leigh, first started in the antiques business as teenagers collecting American stoneware.

The men became celebrities on PBS' highest-rated series, "Antiques Roadshow," and have been part of its team of appraisers since the series began in 1996.

Leslie Keno has been a senior vice president and director of American Furniture and Decorative Arts at Sotheby's since 1983.

Throughout his tenure, he has cultivated relationships with leading Americana buyers, as well as with a broad range of art collectors, including board members and directors of institutions, renowned private collectors and prominent dealers.

With his brother, he published "Hidden Treasures: Searching for Masterpieces of American Furniture" in 2000.

The Kenos were awarded the National Humanities Medal by the president in 2005 for their contributions to the Americana field. Leslie graduated from Williams College with honors in American art and was a fellow at Historic Deerfield.
