Spider-Man is probably the popular favourite. I used to relish my monthly trip to the Smoke to buy comics. I always saved the Spidey ones to read last. X-Men was probably my next favourite.
I had my fair share of comics and sports cards/memoribillia when I grew up. I only went after the 'first appeances' of characters. I have autographs galore.
I never cared for DC comincs
Marvel and small upstarts were cool
I have over a hundred in plastic in the attic for about 20 years now.
X-factor

silver surfer

Borris the bear
Geriatric Gangreen Jujitzu Gerbals
