This official Babe Ruth League Diamond DBR baseball was in with a baseball collection from the 1970's belonging to my grandpa. Diamond brand, 5 ounces, 9 inches. DBR, Cushioned Cork Center, Korea.  I can see some very faint signatures written in turquoise ink.  I have no idea how old it is, but it has a very cool retro look.  It is a game-played ball (as were all balls in his collection), so there are scuffs.

View photos for details and condition. Has been stored in a clean smoke free home for a very long time. 

Please check my other listings. I also have a Pro-Mark SOF-TEE Level 10 ball and would be happy to combine shipping as a savings for you.

Thanks for looking!
