Helvetica Neue Exp Bold (or perhaps Heavy) with the "a" modified by cutting the "q" tail.
The "r" look like it's been made from an "n".
I tried it quickly here and it seems to work.
Hi! Thank you very much! You were really helpful.
I already thought about the posibility that it were Helvetica,
but the "a" was misleading me!! Thank again!
