Jordan Spieth's autograph habits have been under extreme scrutiny this year, and we've even been quoted on the Golf Channel and elsewhere about the sloppy, illegible autographs that he gives to anyone that he perceives to be a professional autograph chaser. And even when his signature is legible, he often signs an abbreviated "J.Spieth."
Because of this, Spieth's early full-signature autographs are coveted by collectors. Offered here is a full-signed Jordan Spieth autographed 2015 US Open flag.
