This week on Vegas Never Sleeps with Steven Maggi, you will meet Brett Maly, who can tell you exactly what that piece of art in your attic is worth. You can see him on the international tv hit, Pawn Stars. Later, part 2 of our conversation with Steve Corkran, author of “Al Davis: Behind the Raider Shield.” Finally, your Vegas Insider, Scott Roeben, tells us what market the Stratosphere is trying to reach.
