Lanciostory #185, Anno IV, Number 43 (1978), story page 1 by Medrano and Alcatena

"Manos rojas" ("Bloody hands") by Carlos Albiac, October 30, 1978. Fifth chapter of the "Press" series.

Translation of last panel: "My career as a war correspondent has been long, and I have decided to tell recent or old episodes (literal translation: 'episodes near or far in time'), without a precise order, simply following the unpredictable and tormented course of memories."

The correspondent looks like Ernie Pyle, famous for his newspaper stories about the common man serving on the front line in World War II. He tragically was killed in action several months before the end of the war during the Okinawa campaign.

The seller identified the piece as being from Lanciostory, a weekly Italian comics magazine that initially published mostly work by South American, especially Argentine, writers and artists, according to Wikipedia.

However, an Italian comics database (comicsbox.it) says the story actually first appeared in Ediciones Record's comic Corto Maltés 38, August 1978, in Argentina and was subsequently run in Lanciostory.

Although attributed by the seller to Enrique Alcatena, the story is signed "A. Martinez" and "E. Alcatena" (see additional image). According to Alcatena, he was drawing backgrounds and filling in blacks at the time as the assistant to Julio Cesar Medrano, whose pen name was "A. Martinez," short for "Adrian Martinez." Medrano specialized in World War II stories. Over the course of his career he used at least 14 pen names, based on GCD entries. He is credited with work in Italian, Argentine, and other European and Latin American comics as well as DC Thomson's Commando in the UK and Charlton war and romance books in the United States.
