Yes, this is the very jersey that Roger wore all day during the 2004 John Hanncock All Star FanFest and was taken right off of his back at the end of the day and signed by him. The jersey is shown being worn by Roger on a Sunday July 11th 2004 ESPN interview. As authentic as a Clemens worn jersey can be, this is a giant size Majestic jersey worn by one of the true icons of baseball history!
