Chess simuls did not necessarily take place in chess clubs. One example is this simultaneous event, advertised by Daor Ha'Yom, which will take place in the 'Eastern Pioneers' Workers' Association club. The latter association was an organization of socialist oriental Jews (link in Hebrew).
The performer is 'the famous chess-player Mr. Sigmund Zehavi' (ph. spelling). I have not been able to find any information about this person. Does anybody know?
