Help for the Unenlightened!

[Aquarian Sports Cards]

I disagree, they are not uniform in intensity, they're not signed in perfect placement, even over the top of printing, and the ball is nowhere near complete. Also don't understand Frankie Drews on the ball unless he coached for STL. I can't say definitively if they are authentic, but I am fairly certain they are actual signatures.

EDIT: OK guessing he got this at a Boston Braves vs Cardinals game in 1944 or 1945. Tommy Holmes was a Brave as was Drews. Drews only appeared in the majors in 1944 and 45. Almost guarantees it's not a stamp. You don't have stamped balls of a handful of players from two teams. Unfortunately multi signed balls without a real theme aren't the most valuable things in the world even with a Musial signature.
