Steiner Sports is currently running an auction that includes various items from the estate of former Dodgers infielder Harry "Cookie" Lavagetto. There's a bunch of stuff from his coaching days, but there are also some goodies from his time in Brooklyn. One of which is featured above. (auction link)
What you see is a business card that was made for Lavagetto by his teammates/peers - no doubt honoring him for his play in the field and leadership in the clubhouse.
As a side note, the auction description relays how Cookie got his nickname:
Lavagetto signed with Cookie DeVincenzi, owner of the Pacific Coast League’s Oakland Oaks.
