I saw a page where Wonder Woman and Spider-Man were there together. I thought it was fan-made, but it was an original comic book.
I've seen the Superman-Spiderman crossover, but when did that crossover happen ?
I think you're talking about Marvel Treasury Edition* #28 from 1981. In "Superman and Spider-Man" (a sequel to Superman vs. the Amazing Spider-Man) Superman and Spider-Man battle the Parasite and Dr. Doom, with the Hulk and Wonder Woman guest-starring.
*Marvel Treasury Edition is an American comic book series published by Marvel Comics from 1974 to 1981. It usually featured reprints of previously published stories but a few issues contained new material. The series was published in an oversized 10" x 14" tabloid (or "treasury") format and was launched with a collection of Spider-Man stories
