From the New York Times, Sunday, April 18, 1965, page 1.
A look at the other photos UPI sent out that day to its subscribers, including the Times, throws the Times' choice into especially sharp relief. I retrieved the five other April 17 photos from UPI’s archives. Two show a mass of antiwar pickets carrying signs bearing readable slogans . . . ; one shows a large mass at the antiwar rally at the Washington Monument; and the other two give an accurate sense of the degree to which the antiwar people outnumbered the counterdemonstrators. All five were, in formal terms, printable; the pictures of the picketers with their signs were elegantly composed, with high contrast and good formal balance. But the effect of the photo the Times chose was visually to equate the antiwar and right-wing demonstrations, and to give the impression — since the photographed segment of the two picket lines were identical in length — that they were equally large.
