They are all in pencil and over the past 70+ years they have faded some.
Are the autographs real? I'm no expert, but they all seem to be in a different style of handwriting. It doesn't look like someone just started signing names. Plus there are some pretty obscure names, which I doubt would have much of a forgery market. I'm going to say that they are the real deal.
The bad news, at least for me, is that all of the autographs are from the Cubs opponent, the St. Louis Cardinals.
The good news is that there is one very famous Cardinal name.
....Stan the Man!!
Musial was a 20-year-old rookie in 1941, which makes this even cooler...a rookie auto of Stan Musial.
So is it real?
The Musial looks pretty good. I may be prejudiced, but I'm going with authentic.
So who else signed?
Pitchers Lon Warneke (a former Cub) and Harry Gumpert
Coach Bubba Wares
Infielder Jimmy Brown
Shortstop Marty Marion....Marion always made a big dot above the I in Marion, so this looks good.
Pitcher Max Lanier
There are others that I couldn't make out. But with just the Musial alone, my outlier 1941 scorecard is pretty awesome!
