Poster-Baseball Centennial

[mjohnson118]

This is my first post to the site so I hope that I am following the rules and placing it in the correct forum.
I recently came across this Baseball Centennial lithographed poster commemorating 100 years of baseball. The image of Uncle Sam appears to be that of a James Montgomery Flagg, but I do not see his signature anywhere on the piece. It has been cleanly cut down the center which allowed it to fold in half and taped on the backside to hold the two halves together to facilitate use as a backer for a picture frame. It also has a couple of small tears. My dilema is this; I would like to have it restored and framed, but the cost is roughly $275. If the poster has no real monetary value I would likely not have it restored. Can someone tell me if James Montgomery Flagg was commissioned to produce the art and what the value is of this fine poster.
