Amazing Spider-Man #102 (1971) Morbius the Living Vampire
The giant-sized, square bound Amazing Spider-Man #102 features the origin story and second appearance of Morbius (Marvel spelled Morbius incorrectly on the cover - check it out!). Lizard also makes an appearance. It has the first (highly-collectible) picture frame cover in the ASM run, drawn by Gil Kane, who also did the interior art. Story is by Roy Thomas. This book is graded 9.4 NM with off-white to white pages by CGC. Its alignment is pretty nice and the colors are vivid.
