The book was published in 1968 in Galicia by Galaxia Editorial. The font looks similar to Kabel Condensed, but it's not. Thanks

Should indeed be Kabel, just the narrow letterpress version, which might not match the digital versions and also can look different in different sizes. 

P.S. Naming the book might help. 

 

Two different pages of this book, called «O león e o paxaro rebelde», of Bernardino Graña.

Thanks a lot

Erbar Condensed Bold seems a better match, but to Ralph's point the digital versions currently available are not quite a match to your sample.

Oh, right! Erbar!

Letterpress sample:

Thanks a lot to both!!! wow! great!

Investigating in Jakob Erbar, I think I could aproximate the solution of my next question.

I open a new case now…
