Vintage Boston Red Sox MLB Baseball Jacket Size Boys 10 Cotton USA.  I am not finding any exact matches, this one is cotton unlike the others that are vinyl.  Hand sewn Red Sox on the back, red sox with ball background on front, I can't find a manufacturer label. Slight fade spot on left arm, elbow, repair to armpit seam on right side.  Still would be the envy of the other kids in this classic.
