The following picture hangs in the Rishon Le'Tziyon chess club. It is Vassily Smyslov giving a simultaneous display in the club during the 1964 Tel Aviv Olympiad (above). The caption says, 'An unforgettable evening of a simul with ex-world champion Smyslov, 1964'.
The web site notes there were 44 players (+37 -2 =5), and gives the names of those who won or drew. The web site adds that 'the building was full to capacity, and the curious climb on the window sills to observe' the display from outside.
Hard to imagine something like this happening nowadays -- in Israel or elsewhere.
