Ulrich Mack was one of the few privileged media representatives officially permitted to cover the entire trip of the most powerful man in the world to Germany, from June 23 to 26, 1963. Working for the magazine Quick, the German magazine with the highest printrun apart from Stern, Mack was never far from the action. The photographer, 28 years old at the time, was equipped with six Leicas – an impressive number. He had outfitted his M2 and M3 cameras with fixed focal distances of 28, 35, 50 and 90 mm, so as never to miss a motif. “After all, I had to be better than the others,” Ulrich Mack recalls.
On Sunday morning, Kennedy and his entourage had landed at the Cologne/Bonn Airport. In Cologne, Mack took the present photograph, resoundingly entitled A Piece of Advice for the American President. Mack numbers it among his personal favourites, recounting in an interview (on ntv.de): “He was diving into the crowd, an unknown phenomenon in Germany until then. There is a picture of a woman almost sticking her finger into his nose outside the Cologne Cathedral. She wanted to tell him what the American President should think. That’s very German. She was a teacher, I think.”
Only a modest series of six photographs appeared in the Quick edition of July 7, 1963, entitled Kennedy and the Berliners – “Nothing in the World Can Separate Them Now.” In November of the same year, John F. Kennedy was assassinated in Dallas, Texas.
