These were shot in the early 1950s on assignment for Holiday Magazine but as with the Robert Capa post, I'm not sure the date of the issues. The first three images are from a chapter entitled "The Low Countries."
The rest of the images are from "The Iberian Peninsula."
The lower left image is by Cartier-Bresson. Top left and lower right: Duncan Edwards; Top center: Arnold Newman; Top right: Slim Aarons; Bottom center: Alexander Wainman.
