1952 Rawlings "Pictorial Sports News" St Louis Cardinals Display Poster 14x17
 

I recently purchased an estate of vintage St Louis Cardinals memorabilia and this item was found while going through the stuff. I have spent the past 3 hours researching and I've come up blank.

Does anyone know exactly what this is?

I dated the poster 1952 due to it saying that it's Eddie Stanky's first year as manager.

Any and all help is appreciated as always. Thanks.

Looks possibly like the center page of a catalog because of the size and center fold.
