Eliezer Pe'er, the captain of the Israeli team to the 1960 Leipzig chess olympiad, came well prepared: he brought with him an autograph book and asked everyone to sign it. Most agreed.
There are the signatures of six world champions past, present and future: Mikhail Botvinnik, Max Euwe, Robert "Bobby" Fischer, Tigran Petrosian, Vassily Smyslov and Mikhail Tal. Other famous players include Salo Flohr, Svetozar Gligorić, Viktor Korchnoi, Andor Lilienthal and Miguel Najdorf, to name just a few. Above we have the Soviet team's signature. Below, the American and Argentine ones.
