Americans in Lebanon march for Palestinian right of return, April 1973

This is an AP wire photo that I purchased off of ebay a couple years back. I don't know whether the photo ever showed up in any news report on the event. A group of Americans, I don't think belonging to any particular organization, put on this event, a two-day march to Sidon. The following year they organized another march, from Sidon to Tyre. (That's me in the middle, with the headband.) I was too involved in marriage preparations to go. The following spring, 1975, no march was organized, it was the early days of the civil war. Two things I notice here: (1) the woman next to me (whose name I forget) is wearing a kufiya, reminding me that expats in Beirut would do this in the early 70s, and (2) I'm carrying a plastic bag from the Rebeiz record store, one of the two best record stores in Beirut at the time. It should be noted that the march proceeded just a few days after Israeli special forces entered West Beirut and assassinated three PLO officials: Muhammad al-Najjar, Kamal Adwan, and Kamal Nasser.
