The Kellogg Co. has unveiled its new prototype of a Corn Flakes box featuring U.S. swimming champion Michael Phelps. 

The 23-year-old winner of a record eight gold medals at the 2008 Beijing Olympics will soon be appearing on Corn Flakes boxes as well as Kellogg's Frosted Flakes.  

The cereal boxes featuring Phelps, the winningest Olympian of all time, are due to hit stores in mid-September.
