Caption: Leaving a second summit in August Malcolm traveled to Kenya...
And as the wiki entry shows, he was in Africa in April and May of 1964. Then Kenya in August. Actually, his conversion to sunni islam dated from April 1964. So it would seem that the 'dedicated civil-rights advocate' spent at least five months overseas in 1964.
The face of the person in arab dress in the montage has been obliterated.
So now we have April, May, June, July, August, September and November...1964.
