Can anyone identify this print in such a way that I might have some luck tracking down a high-resolution image of it?

Thanks!

I did an image search at http://www.tineye.com, which came up with this wikipedia page which calls it Minamoto no Yoshiie, by Tsukioka Yoshitoshi.

Hope that helps. No higher-res images came up at TinEye, but there were some small ones that might have been thumbnails.

I have seen this before, I think it was in IGS's collection of such images. You might find a higher res there.
Should be somewhere here http://www.pandanet.co.jp/English/galleryintro.html
