Ledecky, who won four gold medals in Rio and has five total, posted the 10-year-old photo and the current one to Facebook on Monday.

“Recreating a 10-year-old reverse! Katie was more than happy to sign a poster for the Greatest Olympian of All-Time,” the post read.

Phelps finished his illiustrious Olympic career with five gold medals and a silver in Rio, bringing his total to 28.
