The short answer to your question is "Yes." Any design change and new printing is a variation. Even if just a word or two is different, a whole new printing was required. We list these as varities in our price guide. "Color Variations" are much more controversial. If, to the best of our judgment, the different color was a result of a design change, we list that as a variety. If, however, a slightly different color is a result of the ink fading during a long print run, we do not consider or list that as a variety. Hope that helps!
