A rock concert souvenir is typically something that a fan can take home to remember the experience. The most common items are a TEE (3 letters) and a tshirt (6 letters). A TEE is a short-sleeved, usually cotton, shirt with a round neckline and no buttons. A tshirt is similar to a TEE but usually has a crew neckline and may have buttons. Both items are often printed with the logo or artwork of the artist or band that performed at the concert.
