Exceedingly rare newly discovered collection of twelve St. Louis Browns baseball supplements issued by the St. Louis Republic newspaper, circa 1909. These twelve supplements, along with the twelve St. Louis Republic supplements featuring St. Louis Cardinals players that are being offered as a separate lot in this auction, originate from a recent find in the St. Louis area and for all but one, represent the first examples we have seen. Their rarity is such that they are not even listed in the Standard Catalog of Baseball Cards and we have never handled another. While we cannot state with certainty, we believe the twenty-four supplements offered in this auction (twelve Browns and twelve Cardinals), represent the complete set issued at the time. Each supplement features a photo of the player, below which is a short biography, and the text reading "Supplement to The St. Louis Republic." The twelve Browns players featured in this lot are Rube Waddell, Bobby Wallace, Bill Dinneen, William Graham, Arthur Griggs, Roy Hartzell, Dan Hoffman, Thomas Jones, Barney Pelty, Al Schweitzer, James Stephens, and George Stone. Based upon the players represented in the collection, 1909 appears to be the probable year of issue. Each supplement (9x12"), printed on thin paper stock, displays a tack hole in each corner that has been professionally repaired, except for those of Stone, Pelty, and Hartzell. Aside from the restoration, and minor pencil notations on the front of the Schweitzer supplement, the collection is in Very Good to Excellent condition overall.
