Thanks, guys! Sounds like keep it is the consensus here. I think it's really cool, so that value sounds worth more, I suppose.
I think this rookie Musial might be my "favorite," and seems the most "rare" to me.
It's on a clean page where it wouldn't be an odd shaped cut. It seems to have a lot more history—and would be among his first autographs.
I wonder level of interest in this alone for any Cards/Musial fan especially.
