This looks like a piece of his game used 2022/2023 Nike Brazil Stadium Home Jersey... 5 game used pieces are on this factory sealed card. The large piece in the middle looks to be a piece of his jersey # on the back of his home stadium jersey. It has the sharp diagonal cut purple embroidery outside the green. There also might be an impact mark in the middle center jersey piece (pictured) from when Vinicius wore this jersey in a home game. It's slightly raised and has a darker spot. The item is still factory sealed never touched by collector hands, so that is my professional assessment.
