As its annual kick-off for the Southeastern Wildlife Exposition, decoy and sporting auction house Copley Fine Art Auctions holds its fifth annual winter sale. Complete with world-class paintings and bird carvings, the auction offers a look at, and even a chance to take home, treasures such as a rare Havre de Grace swan decoy, which dates back to 1900 and was likely repainted in 1913 when swan hunting was outlawed. These and more are available to preview until the auction begins on Saturday at 10 a.m. Charleston Marriott, 170 Lockwood Blvd. Friday, 3-5pm; Saturday, 8:30am-10am. Free.
