That pic is a hoax. However, there are at least 2 others than aren’t. I’ll see if I can find them.
Oops, well “fake but accurate” applies!
From the communist North Vietnamese-supporting "Vietnam Veterans Against the War" website:
Was John Kerry photographed with Jane Fonda?
Both John Kerry and Jane Fonda spoke at a VVAW rally in 1970 at Valley Forge, PA. (Brinkley, 344-345; Nicosia, 68-70).
There is an alleged photograph of Fonda and Kerry listening to other speakers at that rally. Kerry is seen several rows back in the bleachers from Fonda.
The photo was reportedly purchased by Ted Sampley for $179 from an anonymous source.
