So this is blowing up a little on the comic related social medias - I'm not sure if it's ever been talked about here, but here's the gist from a user named "comickeys" on Twitter:

In the 1970's, publisher La Prensa did not believe Mexicans would read Spider-man after Gwen Stacy died. They created 45 original issues after Spiderman 119 where she lives, that have never been translated or reprinted. This is their marriage issue. Marvel needs to collect these!

It's amazing that there's about 4 years worth of untapped adventures (except for the people of Mexico) in basically what's an alternate universe, where Gwen Stacy remained alive and Peter's main squeeze. I'm surprised that such a series hasn't been collected for English audiences, if the author is to be believed.
