Jordan Spieth's autograph habits have been under extreme scrutiny in recent years, and we've even been quoted on the Golf Channel and elsewhere about the sloppy, illegible autographs that Jordan often gives. And even when his signature is legible, he usually signs a small, abbreviated "J.Spieth."

Because of this, Spieth's early full-signature autographs (especially on 2015 Masters flags) are coveted by collectors. This is a prime example of a high grade Jordan Spieth full-signature 2015 Masters flag.
