Beatles AUTOGRAPHED Sgt Pepper Original Mono Tape Record (READ BELOW)

THIS AN EXTREMELY SPECIAL ITEM THAT IM SAD TO BE PARTING WITH. WHAT WE HAVE HERE IS AN ORIGINAL 1967 SGT PEPPERS 3 1/4 IPS TWIN TRACK MONO TAPE RECORD WITH THE SIGNATURES OF ALL 4 BEATLES WITH PAUL MCCARTNEYS SIGNATURE ON BOTH THE FRONT AND THE BACK OF THE RECORD. I GOT THIS TAPE FROM MY GRANDPA, WHO SAID THAT HE BOUGHT THIS FROM A FELLOW WHO DISCOVERED IT IN A STORAGE UNIT. SINCE THIS DIDNT COME WITH A CERTIFICATE OF AUTHENTICITY IM NOT 100% SURE OF ITS AUTHENTICITY (this is why the price is so low). PLEASE DONT HESITATE TO ASK ANY QUESTIONS.
