This extraordinarily rare 1937 letter contains the rather elegant fountain-pen signatures of two Brooklyn Dodger honchos, president Stephen W. McKeever and VP James Mulvey. In the agreement McKeever gives permission to an advertising agency to use his name in ads for Bigeloil liniment. However, the signifiant one here is really Mulvey, an underlooked figure who also was president of Goldwyn Studios and helped to manage the team's move to L.A. in the 1958. 6 x 7" with mild wear and the lightest of fold marks. EX all around.
