FM Allan Savage (the link is to his chess homepage) shares with us an envelope from the Third International (Preolympic) Tournament, Nethanya (נתניה - also spelled Natanya, Netanya, etc.), June 1964.
It was one of three international tournaments in Israel that year -- the other two being the Tel Aviv Olympiad, and a small tournament in Jerusalem which "recruited" some of the Olympiad's players. All were mentioned in this blog (look under the "tournament" label).
To avoid a possible misunderstanding, 'preolympic' does not refer to any official FIDE designation of the tournament, but simply to the fact that this (individual, not team) event took place before the Olympiad, which, as the link (to Olimpbase) notes, took place later in the year than usual -- in November -- due to the climate.
