Bradley Knit Wear Major League age identification

[Lisa Rinehart]

Hi, I recently picket this item up at an estate sale. I do not know the age or school that the O represents. I am however looking for some assistance if anyone is familiar with Bradley clothing. I plan on loading the image to the database once I receive more information.
I really appreciate it, Lisa

They seem to have been very popular starting in the 1920s. Apparently in “the mid-1920s, the Bradley Knitting Company began an affiliation with Major League Baseball by offering the “Bradley Big League Sweater” to youngsters and fans of the game through advertisements in Baseball magazine.”

From a 1924 publication:
“Bradley Big League Sweaters were worn by practically every team in both the National and the American leagues”

Here is a tone of info on the company from Lizzie Bramlett (AKA fuzzylizzie)
