The #1 Linkin Park Undergound newsletter, is personally hand signed by all six members, including the late great Chester Bennington. I have included proof photos of this rare piece being signed that have been water marked and will be included. Authenticated by PSA DNA and a letter is included from PSA DNA as pictured, this piece is a rare find that will make a great addition to any collection. Don't miss out on the opportunity to own a piece of music history!
