This is not the first or only AQUILA THE LAST EAGLE comic. Other incarnations include:
AQUILA THE LAST EAGLE, the original art school graduation project, now archived and unchanging.
THE AQUILA THE LAST EAGLE RESTORATION PROJECT, which continues in the "1942 text comic made during the war" spirit of the original graduation project and is in continuity with AVI & AQUILA.
Aquila also appeared prominently in ANNIE FOREVER, which is also in continuity with AVI & AQUILA.
You do not need to have read any of those to follow AVI & AQUILA, which is intended as a fresh jumping-on point for readers new and old alike.
