This is NOT a vintage baseball card.  It is an original art card made within the past 10 years and resembles the Tobacco Cards made in the early 1900s. The corners look like they have been cut but that is the way the card was made.  The card measures "1 3/8" By "2 5/8"

Eddie Grant played MLB from 1905-1915.  According to Wikipedia "Grant was one of the first men to enlist when the United States entered World War I in April 1917, and he served as a captain in the 77th Division. During the fierce battle of the Meuse–Argonne offensive, all of Grant's superior officers were killed or wounded, and he took command of his troops on a four-day search for the "Lost Battalion." During the search, an exploding shell killed Grant on October 5, 1918.^[2][5] He was the first Major League Baseball player killed in action in World War I.^[6] He was buried at the Meuse-Argonne American Cemetery in Lorraine, France."
