Only known proof cover for May 1911 issue of Baseball Magazine. Spectacular cover with fans in the trolley on to the ballpark, with Johnny Evers Article below, "How Chance Became A Leader." Blank-backed, it measures 12x9" and is NM. This is a gorgeous color lithograph and 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.
