Recently, we published our lists of The 9 Vintage Items No Self-Respecting Giants or Rangers Fan Should Be Without. We’ve told you what we’d collect (a Nolan Ryan signed baseball; a glove worn by Willie Mays). Now it’s your turn to show us what you’ve got. This week, while the players slug it out in San Francisco and Arlington, Giants and Rangers fans are invited to show off the best pieces of memorabilia from their collections.

Rangers Fans:

* We’ve built a Rangers page for you.

* Click here to show us what you’ve got.

Giants Fans:

* We’ve built a Giants page for you.

* Click here to show us what you’ve got.

At the end of the World Series, we’ll choose a winning team based on the number—and quality—of submissions we get from you, their fans.

Play ball!
