A carved carousel horse head; a hothouse flower composition painted by Victorian English watercolorist George Kilburn; and a spangled Elvis costume.

ANTIQUES ROADSHOW's final hour in the pork barbeque capital of the world, Memphis, Tennessee, finds its appraisers at the Memphis Cook Convention Center ready to dive into a heaping helping of curiosities and treasures. Some of the piping hot items they find include an exquisitely carved turn-of-the-century  carousel horse head; a hothouse flower composition painted by Victorian English watercolorist George Kilburn; and the obligatory Elvis collectible - a spangled Elvis costume that, if traced back to his 1968 comeback tour, could rocket its value from $15,000 to $100,000.
