My favorite mementos are
An 8X10 picture of Babe Ruth and Dutch Reuether when they were on a barnstorming trip - My Grandad gave it to me - he was a semi-pro catcher who played in the game.
My Dad's first professional contract and the newspaper article when he hit a homerun in Yankee Stadium to win (and pitch) his team to the NY City Championship in 1947.
A picture of my Dad - and my uncle (Mom's only brother) - in Yankee Stadium - teammates.
Mt eldest son's game ball from the NY State Sectional championship game.
My glove (a Cooper) - which I purchased for about $10 in 1972.
My youngest son's picture from his 1st baseball team.
Talk about being a pack rat. LOL
