The artwork is based on the band's 1982 album 'Battle Hymns'.
I'm loving the gold glitter thread on this one a lot! I think the black background was a good choice since it brings out the eagle statue a lot more. The only downside to this patch is that I wish the shading / thread rendering was more stronger since the shading kind of gets lost from looking at this patch from a far. Other than that, this is a pretty good patch.
