Helping a good lady....Red Sox sweater info...
 

Interesting find, but I would question the buttons as well - but can see why there was interest due to the label (1920s), you would have to really look at this in person - but if all checks out, this would be a great item!

It's just one of those items that needs to be checked by the next owner, you take a chance in this hobby and I am sure more info can be found out about it when it's in the right hands.

I think that looking at the tag/letter/button stitching and mothing on the 'RED SOX' letters, under high magnification, would give you your answer as to whether or not this is the real deal.

Sewing on authentic era buttons would be no big deal, and matching them with authentic Red Sox sweaters wouldn't tell you much, since at least two other companies appear to have made sweaters for the Red Sox. The thread that attaches the buttons would tell you more.

I owned Dick Hoblitzells 1910 era Reds sweater and all the buttoms were different as they would rip off and then he (or his wife) would find random buttons and sew them on. In my case the sweater had TONS of wear and use so it made sense that the buttons would be replacements, and this sweater looks like it was never used.
