Rare proof cover for November 1912 issue of Baseball Magazine by Gerrit Beneker. Special World Series issue shows old time radio scoreboard with throngs of cheering fans throwing their atypical straw hats in the air. Heavy fold for mailing, o/w VG-EX with artist's notes on verso. Blank backed, it measures 13.5x10.5". 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.
