There's no better way to display team pride than to wear it.  Red Sox fans have a collectible pin  to do so:

• The Red Sox hat pin measures 1.25" x .75" and is gold-plated

Each pin is made from die struck metal with hand applied hard enamel colors and is polished to a smooth finish. The pins have a butterfly clutch that allows for easy attachment to a lapel, hat or backpack, among many options.
