This is a Kristaps Porzingis signed NBA Debut ticket stub (10/28/2015 NYK vs. MIL) signed with "NBA Debut" inscription. This has Steiner Sports authentication sticker which means the autograph was witnessed and is 100% authentic. Ticket is in really good condition and w/ bold autograph. This is also a really rare ticket and not many of these around especially not with a signature and inscription like this one.
