I do not remember which issue it was, but it definitely was a Spider-Man book.

But I remember seeing a German edition of Amazing Fantasy 15 (called Spider-Man 1) for 20 Deutsch Mark, maybe 20 Dollar today. It was a lot of money for a comic book at the time, but I wanted to have it so bad. My mom said no way, for that kind of money I could buy 10 comic books. I made clear that it wouldn't make a difference for her because she wanted to spend 20 on comic books for me anyway. So she bought it, and I was so happy for a very long time. It was a real gem and raised in prices up to 1000 Euros, or Deutsch Mark, I don't remember. I still have it, the value isn't there anymore, but that doesn't interest me. I took me 22 Years to get the first 137 issues of Spider-Man and complete the collection.
