In Pittsburgh, Pennsylvania, host Mark L. Walberg and appraiser Alasdair Nichol head to the Andy Warhol Museum to check out some early works of the Pittsburgh native from his pre-Factory days - eclectic illustrations that garner ample attention from today's collectors. Highlights include intimate correspondence between Cole Porter and actor Monty Woolley; a finely knotted circa 1920 silk Kashan rug; and one of the best flea market finds of all time: a 17th-century Chinese rhinoceros horn cup, purchased for $1 and valued at $350,000 to $450,000!
