The word ‘Gaiman’ here is an abbreviation of “Gaikoku no manga’, literally, ‘foreign comics’. This refers to comics translated from foreign work and published in Japan. For those of you who fret over what is comics and what is manga and bug-eyed-styles and all that, here you go: ‘Civil War’ translated into Japanese and published in Japan becomes manga, and can even get nominated for a manga award. You can keep your Western biases to yourself, thank you.
The list of comics nominated since the award was instituted in 2011 shows a curious mash-up of titles, including the aforementioned Marvel title; Superman: Red Son rubs shoulders with the likes of Nicholas de Crecy’s Celestial Bibendum (French), Schuiten and Peeters’ Les Cités Obscures (Belgium), Lat’s Town Boy and Kampung Boy (Malaysia), Joe Kelly and Ken Niimura’s I Kill Giants. All of which make for great, solid reading — though the jury’s still out on The New 52: Shazam, which managed to make an appearance on the 2015 nomination list. (The previous sentence is vague hyperbole, the prize went to Sweden’s Sayonara September, by Åsa Ekström)
One thing to note: the titles nominated are based on translation date, and not on publication date. This causes similar confusion as the ‘Best US Edition of International Material (Asia)’ Eisner award, where classic material ends up being nominated alongside newer ones, just because they were translated the last year. In 2016, a work by Shigeru Mizuki from the 80s (Showa: A History of Japan) beat the contemporary Master Keaton and Assassination Classroom in the Eisners.Doesn’t that make it overly confusing to judge something that is fresh along with another that has been coated with the patina of time and generational acceptance?
