This is my personal set of 1968 World's Champion Detroit Tigers Volpe Drinking Plastic Glasses/Cups  Try putting a set of these together - it is a real challenge -  they are over 60 years old and few have survived all these years later!  I have 11 of 12  Hank Aguirre, Norm Cash, Don Demeter, Bill Freehan, Willie Horton, Al Kaline, Dick Mcauliffe, Denny McClain, Joe Sparma, Don Wert.  Glasses are in excellent condition except Don Demeter has a hairline internal crack on the left side and Norm Cash has a crack on the bottom with some discoloration - both still display perfectly fine as these flaws don't show.    See the 5 pictures.   E-mail with any questions.
