Valueing a Spider-Man comic book dating 35 years!

[Harakiri]

Hi there. I have this "portuguese" Spider-Man magazine wich is very old, wrinkled on the edges and the first three pages were scratched with a marker. Still, i consider that's in very good shape according to it's age. Ironically the only clue that i've got from it's release date was the "Munchen '72 Olimpic Games" ad that covers the back cover.

Do you guys know if these magazines have market value?


I couldn't find any information about it on specialty websites and as soon as i can i'll try to scan the covers for a comprehensive look.

Some information about it:

Spider-Man #18

Desmascarado por fim (Unveiled at last)

Edited by "Palirey Banda Desenhada"

Copyright by Fleetway Publications, etc.

Any info about this matter?

Thanks in advance!
