i'm no sox expert but i don't think it's team issued. i can't even identify the style. it looks like the home pullover game jersey (not BP) that they wore from '82-'86 but those had nobs and the back numbers weren't red. it doesn't look like any BP shirt that i know of. have also never seen that kind of majestic tag on a gamer.

my guess is that it's either a retail shirt or a minor league shirt. either or. you could email d. miedema over at mears for a conclusive opinion.
