1909-1913 M101-2 Sporting News Supplement Grover Alexander. Graded PR 1 by PSA. This is the one of only three examples of this particular supplement graded at this level by PSA, with just two graded higher. 1911 was Grover Alexander's rookie season and while not everyone considers M101-2 cards, this is undoubtedly Alexander's earliest issue and one that can be rightfully considered his rookie card. This piece originates from a remarkable complete set of M101-2 Sporting News Supplements that was obtained by a longtime collector decades ago. The set, as a whole, is perhaps the finest ever assembled, the majority of which is being broken up and offered in several lots in this auction. (The PSA highest-graded Joe Jackson M101-2, which appeared in our Summer Classic Auction and realized a record price of $20,419, originates from this same set.) The 1909-1913 Sporting News supplements were printed on extremely thin paper stock and nearly all surviving examples display a myriad of significant condition flaws, including creases, tears, and corner chips. The offered supplement is free of any major defects and suffers only a tiny diagonal crease in the lower right corner, a light crease in the center, and a few peripheral creases. Most are only visible from the reverse and the supplement presents as Excellent.
