Hey Guys,
Can anyone tell me who this Brooklyn Dodger is or any info about him. I have only seen this autograph of him. Ive checked ebay for years and after this one I have never seen anything signed by him. I did a google search and there doesnt seem to be any in about him out there. Does anyone know about him or have ever heard about him. one person even told me that he might have been the brooklyn dodgers batboy. anyone ever seen another autograph of his out there? any and all info/help would be greatly appreciated.
