It was one of those photogenic if historically insignificant moments when one (bona fide) icon fleetingly met another. Queen Elizabeth II met Marilyn Monroe at a London film premiere in 1956. The women probably had precious little in common aside from their age (both were then 30), global fame and glamour. A cameraman recorded the moment for posterity and, as luck would have it, Andy Warhol went on to make silkscreen prints of both women.
