Most people probably don't think of fine art among the entertainments on the Las Vegas, Nevada, strip. But ANTIQUES ROADSHOW host Mark L. Walberg and appraiser Alan Fausel discover the work of modern art masters when they visit the Guggenheim Hermitage Museum at the Venetian Resort Hotel. Surprising finds abound at the Las Vegas Convention Center, too, including a charming circa 1865 pottery pig canteen, exhibiting a variety of southwest American Indian characteristics; a fitting tribute to Las Vegas, two pieces of Elvis Presley memorabilia - an autographed record album cover and a macrame belt worn by the King at a performance in the 1970s; and a scrapbook inherited from the owner's great-great-grandfather who collected the signatures of many of the Civil War era's greatest public figures, including Ulysses S. Grant, William Tecumseh Sherman, Frederick Douglass, Booker T. Washington, Robert E. Lee and Jefferson Davis, valued at $75,000 to $100,000.
