Apparently, it was, according to ANN at least.

The Executive Committee of the Harvey Awards and Baltimore Comic-Con have announced the nominees for the 2008 Harvey Awards. Yasuko Kobayashi and Kazasa Sumita’s Witchblade Takeru manga (Top Cow/Image) earned a nomination in the Best American Edition of Foreign Material category.

I’m not really familiar with this award. Perhaps its more of a remark about how good the localization is, regardless of the original material? I doubt it, though, since awards are judged by comic artists. Of all the manga to get nominated, I don’t see why Witchblade was one of them… I read the first volume (kinda quickly, though) and didn’t find it particularly special or interesting, tough the art was nice (I think?)

Anyway, since I actually have more time on my hands, I might as well re-read it. I don’t remember a single thing from the manga XD
