Knut Hamsun - Hambre
Castellano translation of Hunger, by Buenos Aires-based publisher EDITORIAL TOR. The cover is signed either ‘odazo’, ‘cd azo’ or ‘D A Z’ with flourishes. Searches for the artist so far have thrown up nothing.

This book was finished printing in the Editorial Tor graphic workshop on the day 10th of August, 1942.
