What do Brittany Snow, the Jonas Brothers and Ashley Greene have in common?

All five of them have signed baseballs to be a part of SUBWAY Baseball DeSIGNS tour, a collection of baseballs decorated by Little Leaguers and signed by professional athletes and celebrities. The 40-baseball display has been making tour stops across the country and is currently set up at the Little League Baseball World Series in Williamsport, PA.

The baseballs — which include signed balls from Ryan Rottman, Jackson Rathbone, Chace Crawford and more — are also viewable at SubwayKids.com.

The balls are up for auction NOW on eBay through its Giving Works program. All the proceeds generated will go to support the Little League Urban Initiative. It ends THIS SUNDAY, August 29th, so hurry and bid!
