We have sent information to Edward Winter about a Boris Spassky simultaneous display in Israel, 1964, and he had graciously published it in his well-known Chess Notes (#11513). All details about the photographs and credits for finding them is to be found in the link.
We add that the Spassky simultaneous display was in Ein Harod on Saturday, Nov. 28th, 1964, according to an article in Kol Ha'am (Nov. 23rd, 1964, p. 3), which lists all of the simultaneous displays the USSR team was planning to give while in Israel.
