If you read the comments, you will see that Mr. Kenner says that the cups were made for him by Tim Star, who works at "Creations by Star." It is under my impression that he no longer makes this kind of cup.
Dai Vernon cups? Paul Fox, Stanley (Porper) and maybe sherwood most resemble the cups he used, and the price range is 400, 800, and 1600 dollars for a set of 3. Where did you see Vernon's cups anyway?
