So I saw this on twitter and it's an amazing thing that's apparently even surprised comics pros like Kurt Busiek, Gail Simone and Dan Slott. The thread says it best:
https://twitter.com/comickeys/status...24779213275136In 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!

Here's a reddit thread with some additional info on this.
Hopefully, with this catching so many pros off guard, Marvel will make an effort to translate and collect these!
