The Bemis Center for Contemporary Arts will hold its 13th annual auction Saturday.

It's a celebration of the Bemis Center's 30th anniversary, a showing of contemporary art and a precursor to the museum's largest fundraising event in October. The exhibit includes nearly 400 works from local, national and international artists in all media. It will span across the Bemis Center's first floor and underground galleries at 12th and Leavenworth Streets.

Everything in the exhibition is available for purchase at the two separate auctions — the Bemis Underground Auction on Oct. 13 and the Art Auction Gala on Oct. 15 — or online at bemiscenter.org.

The World-Herald held a drawing for a pair of free tickets to the gala earlier this month. Paige Mathew of Omaha is the winner and can collect her tickets at the Bemis Center's will call. Information: jloza@owh.com
