The indicia says that all the pages were lettered by Pat Brosseau, except for pages 19-21 (21-24 by my method) which were lettered by
Rick Geary, and pages 29-31 (31-33 by my method) which were lettered by Hunt Emerson. There must be a mistake, because the story lettered
by Rick Geary is four pages, not three. And I honestly can't tell the difference between Pat's and Rick's style of lettering. They look identical.
