Yes, I meant the image size, sorry I was vague. So this would be a small (edit: actually medium) folio size. But usually originals were some number of 16ths of an in inch beyond a whole number in one (or both) dimension. And this varies from each each of their prints, rather than being standardized. Where are finding an original with these dimensions?Same as originals 14 by 9 from ink most were cut to fit in frames from edge
Also important is the Exact measurement of your print, and compare it to known originals.
