I want to work on a translation of a comic, but I want it to be as close to the original as possible. So I'd like to use the same font used on the issue... I think it's a popular font, 'cause I'm pretty sure I've seen it in another comic. If someone knows please tell me! I'd be very grateful.

Kubert  Sugerido por Heron2001 

I don't know if anyone will find an exact match. But if you'd like a few choices of similar fonts...
Comic Crafts: Dave Gibbons http://myfonts.us/td-hc4V0r
Comic Crafts: Kubert http://myfonts.us/td-CcazOe
and on dafont Kimmun: https://www.dafont.com/kimmun.font?text=THIS%2C+TOO%2C+WILL+FALL.+THE+BURROWING&psize=s

If I had to choose - I'd go with Kubert.

Thanks a lot buddy! Very helpful
