Editorial Verbo is a portuguese publisher in operation since 1958. Its market is composed of most of the portuguese speaking world, namely Portugal, Brazil, Angola and Moçambique.
Verbo is a household name in the portuguese written word panorama, ranging in catalog from original literary exclusives to international literature classics, from dictionaries and encyclopedias to academic textbooks and comics.
Of more pertinence to RPGGeek, though, is their publication of 38 Fighting Fantasy gamebook titles, in portuguese of Portugal (there was already a Brazilian edition by another publisher). This series ran from 1985 to 2003 and was based on the original Puffin edition, using the same cover illustration and green back cover and spine template.
