Baseball Autograph Book from 1942 (Ott, Stengel, Musial, Reese, Lombardi, 1942 WS Cardinals, more)
There are more than 80 signatures in this book including 9 HoF—Mel Ott, Casey Stengel, Pee Wee Reese, Stan Musial, Lloyd "Little Poison" Waner, Paul "Big Poison" Waner, Ernie Lombardi, Enos Slaughter, Billy Southworth, also Hiram Bithorn (the first player from Puerto Rico) and more.
There's a Stan Musial that is before his 1942 rookie season. He played only 12 games, in 1941, at this point.
Also it being 1942, it's pre-war and a majority of these guys went to military service after this.
I feel like this fits both forums, so if the title intrigues you, see my post with pictures and discussion in that thread.
