Shimano Silver Cup

I won a lot of japanese items in a local auction recetnly, One of the items is silver cup that says shimano on the bottom and contains several markings, presumably, in japanese. I was wondering if anyone could tell me more about what the markings are. I understand that this cup was distibuted to major cycling manufacturing execs and distributors. It is very noce, but I have no clue as to the value
