Great fun for the last day of school! Just ask classmates to sign your shirt with any permanent marker (not included) to create a one-of-a-kind keepsake. Our Class of 2008 autograph t-shirts are made of a soft, cotton/poly blend fabric and are available in adult sizes M-XXL. We personalize shirts with any year, name up to 10 characters, and school name, up to 25 characters. Machine washable.
