Dani Futuro comic books

I just bought these issues of the classic comic book series Dani Futuro. I had the middle one as a kid and loved it so much. It was both scary and fun at the same time. It's a Spanish sci-fi series created by Carlos Giménez and Victor Mora in the sixties. These Swedish editions were released in 1983 though and I bought my first copy as a kid in the early nineties.

Does anyone else out there remember this comic?
