Hello Rockers! I'm new here and a first time poster. I was wondering if anyone had some insightful knowledge to share with me concerning an ACDC "Highway to Hell" album. It's a tough one. (This was handed down to me to say the least) There is no vinyl with the sleeve, but, the sleeve is signed by Angus Young, and is also presented with a certificate of authenticity. The sleeves condition is so-so, dings and Knicks on all four sides, not very well taken care of before me. Is this sleeve worth anything? Can it be with something with a vinyl included? I must have insight! I will post pictures by request!
