Opening Day Old time stadiums baseballs by Unforgetaballs.Each of the 3 balls represents one of the original stadiums opening days.(Fenway Park,Yankee Stadium and Wrigley Field).This design is by Emily Wolfson and comes with a COA.(Last picture).Only 100,000 printed.Comes in the ballcube(1 has a scratch on top).Only 3 stadiums in this set.Running out of room so it's time to add to someone else's collection.Smoke free home.They retail for $30 a piece on their website.Ive had my 3 for a couple of years.
