A gentle reminder:
If you are writing about pageless Jimmy Corrigan, try to be as clear as possible about when your sequence starts and ends, such as “I will be looking at James’ visit to the White City, from the full-page panorama to the final image, five pages later, of James in a nightshirt.”
You may footnote this description if you find it too clunky.
You could also add an appendix with a scan of the first panel/page. See the sample essay for an example.
