It took me years to get one that I both really liked, and that was in my price range. But after due consideration, and a not insignificant chunk of change, I was able to acquire a lovely original art page by one of the masters of the form.
It's from Our Army At War, issue 133, page 9. Or, if you like, Sgt Rock Archive number 4, page 166.
And if I say so myself, it's glorious!
