You haven't seen the last of Michael Phelps, 28, who is heading into retirement as the most decorated Olympian of all time. Get ready for Phelps' face — to say nothing of other select parts of his anatomy — to be featured prominently in press and endorsements, beginning with a Louis Vuitton ad shot by celebrated photographer Annie Leibowitz, 62.

In one of the Vuitton ads, Phelps is dressed up in a three-piece suit, sitting on a couch, appearing to chat and sip tea with fellow legendary Olympic gymnast Larisa Latynina, 77, the previous record holder, before Phelps, for the most Olympic medals ever won — 18 between the years of 1956 and 1964.

Then, in an ad for a Vuitton carryall bag, Phelps is photographed in the bathtub, wearing a small speedo and a pair of tiny goggles, the rest of his clothing stuffed into the bag at his side.
