Relatives of legendary sharpshooter Annie Oakley are offering up a collection of items — including her Stetson hat, guns, letters and photographs — in an auction that one expert says hits the mark for its breadth and sentimental value. On Sunday, Heritage Auctions will offer up about 100 Oakley-related items in Dallas, including a 12-gauge Parker Brothers shotgun that is expected to fetch about $100,000. Two Marlin .22 caliber rifles are expected to sell for more than $20,000 each. Oakley gained fame in the 1880s and 1890s for her shooting skills as a performer in Buffalo Bill’s Wild West show. She died in 1926 at the age of 66, but has remained a pop culture icon. Over the decades, her likeness has appeared on everything from dolls to lunchboxes and her life story inspired a Hollywood movie and Broadway’s “Annie Get Your Gun.” The photos in the auction include several of Oakley hunting with her dog, Dave, and more formal shots of her posing with a gun. A promotional mini-postcard that Oakley sent William Butler has the words “Compliments of Annie Oakley” on the front with an adjacent heart that’s been pierced with a bullet. … “Click and Clack,” the mechanics-turned-comedians who launched one of the most unlikely — and most beloved — talk shows in radio history, have decided that 35 years at the wheel is enough. Brothers Tom and Ray Magliozzi announced Friday that they will no longer record new episodes of the weekly call-in series, but it will continue to live on in syndication. The show was one of NPR’s powerhouse performers. People who had no interest in cars, or weren’t the least bit mechanically inclined, were among the most devoted listeners — tuning in for the radio magic that took place when the brothers began playing off each other.
