STYX CORNERSTONE VINYL COVER SIGNED BY DENNIS DEYOUNG & CHUCK PANOZZO.  It is signed very nicely in blue sharpie on the front.  The cover does show alot of wear as you can see in the photos but does not take away from the autographs.  The sleeve is in very nice condition.  There are no smudges or skips in the autographs. The band was inducted into the Rock & Roll Hall of fame. It was released in 1979.  The LP is included.  I have played the entire vinyl and it sounds great.  This item has an affixed Beckett Authentication Services (BAS) authentication sticker, which includes a scannable QR code to verity authenticity.  Please note that Beckett no longer provides serial-numbered COA cards, and the attached BAS sticker will serve as the complete authentication for this item.  The cert number is BH027853 which is attached to the back of the cover. Please check my feedback and bid with confidence.  I have been obtaining AUTOGRAPHS IN PERSON for over 40 years at hotels, games, spring training, concerts and more. Please check my other items.  Thank you.
