I've called this Kodachrome slide, 'Fisherman in Greece' but to be honest there are several assumptions in the title that are purely guesses on my part. I don't know that the central character in the picture is actually a fisherman - it's possible he is picking up what looks like a squid to place it in the pot in front of him and cook it.
I also don't know for certain that the location is Greece, although the writing on the boat looks to be Greek, and the slide was with several others that I've found to be located in Greece so that does seem likely.
The date is more certain because the slide has the date printed on it, so we know that the slide was processed in May 1968 and therefore probably taken within a month or so of that date.
