I’m assuming you bought the one with MeiGray serial # H06328.
That jersey was prepared for use in the Skills Competition at the 2011 All-Star Game. Both red and white jerseys were issued for Keith, who wore the red one in the competitions, so the white one remained unused, so it should be considered “event-issued.” I believe EPS would have lettered those, so look carefully at the lettering, and there will be slight differences from the on-ice ones lettered by CSL. The E in Keith will have a center post that’s a bit too long, and the stitching should be extremely tight, with a stitch length that is ever so slightly shorter than what CSL does.
