Help identify/locate a higher resolution image of a Wolf Kahn Painting?

I’m planning on copying a Wolf Kahn painting, but the only image I could find of it on the web was this low-res image. I was hoping to find a higher-res image so I could get a better idea of the brush strokes. Even just the name of the work might be helpful in figuring out how to find it. Any help/advice would be greatly appreciated.

I’ve never really painted before, but my mom is pretty talented and she offered to teach me. I was hoping to use this one as a starting place.
