ANTIQUES ROADSHOW host Mark Walberg and appraiser Caroline Ashleigh corral a collection of vintage rhinestone-studded, western-style garb created by the late Nudie Cohen, westernwear outfitter to the stars. Back at the convention center, appraisers round up some outstanding finds, including a rare collection of barbershop shaving mugs, bought for "two bits" each in the 1930s; a valuable assortment of Anna Richards Brewster paintings purchased for a fraction of their value; and a collection of original Charles Schulz "Peanuts" comic strips and artwork, given to the owner as a gift by Schulz, estimated to be worth $150,00 to $200,000.
