Original vintage 3.5 x 4 Major League felt patch honoring the "Baseball Centennial, 1839-1939," featuring a classic red, light cream, and blue design by Marjori Bennet portraying a batter centered within a diamond. All 16 teams wore the commemorative patch on their left sleeves with the exception of the St. Louis Browns who wore it on their right sleeve. In fine condition, with slight loss to the upper right corner. More information about these patches can be found here: http://1939baseball.com/centennial_patches.html
