Do you happen to know the year the trophy was won by Larry "Buff" Vendetti?
I tried looking it up without success.
I am glad that the trophy got to its rightful owner.
To know the exact day you will probably have to go to the library and search in the microfilm archives the sports section of the New York Times
It has to be from no later than 1964, when Duncan declared bankruptcy. The back of the 1963 trick book has a very similar trophy, except that the base is a trapezoid and the circular base does not say Duncan but only has a leaf motive (exactly like the one I have). We also know that at least as early as 1956 they were giving trophies with tops positioned like that, although the one I have has an extra large top (not real size). I am pretty confident that it is from sometime between 1955 and 1964, most likely between 62 and 64. But my gut feeling is 1959.
