Only known proof cover for August 1911 issue of Baseball Magazine. This "Players' Number" features incredible Cleveland Naps lineup riding in old baseball trolley: Nap Lajoie, Cy Young in his final season (although he did go back to Boston for his finale), and a young Shoeless Joe Jackson in profile behind Old Cy. Sent to the artist and somehow rejected the art is by and from the collection of the preeminent "Baseball Magazine" cover artist Gerrit Beneker. Blank backed, it measures 9x8.5"and is NM. Gorgeous color lithograph with the white matte border is a work of art of far better quality than the final covers off the newsstand. Recently discovered from the hands of Gerrit Beneker (1882-1934), the master illustrator who did covers for a myriad of publications of the early 20th century. He is best known however, for the 30 covers he painted for "Baseball Magazine" during their key formative years of 1911-14. These works defined not only the look and feel of the first ever U.S. baseball monthly magazine, but for baseball illustration art for decades to come.
