One of the most popular issues in the ASM run, Marvel did a $1.75 cover reprint 30 years ago.  So does that make this a Copper Age or a Bronze Age key??  This book features the first appearance of Morbius, the living vampire, which was originally released in 1971.  It's a really nice looking reprint, with a beautiful silver metallic background.  This book is graded 9.8 NM/MT with white pages by CGC.  If you can't afford the original (we have a beautiful copy of the original for sale, too), this is a VERY NICE substitute.
