Vintage 1930s Baseball Autos: Who are These Folks (may be Lefty Grove, Jimmie Fox)?

[meatloaf]

I came across these things the other day; it looked very intriguing to me, but I don't know much about this potential era and these players. From what I know, all of these are raw; no 3rd party authentication whatsoever. There are two sheets of autos and a auto ball. One sheet is two sided; the other is a single sided.

It appears the 2nd page of the 1st sheet has an auto of "Lefty Grove." I assume this is MLB HOFer Lefty Glove, correct? The second sheet has an auto of "Jimme Fox." I assume this is MLB HOFer Jimme Foxx, right? Because I saw these names and from the "date" on the first sheet, I assume these are baseball player autos from the 1930s, correct? I am trying to connect if they are all from a single team, from an all-star game roster, etc.? I looked up the world series for 1930, it was done before 13 Oct, the date on the 1st page of sheet 1. There is a reference to American League All Stars" from the sheet 2. Not sure if that has any significance. Additionally, I have little experience in valuing multi-auto balls or sheets from the vintage era. Is this worth anything? If so, what kind value at an auction assuming authentic? Does the kid's "ownership" statement on sheet 2 decrease the value? Are these worth submitting to PSA/DNA for a Q.O.? Finally, is the Teddy Ballgame auto on the ball likely legit? Thanks! Meatloaf
