The 2011 edition also runs to 192 pages so I imagine they will simply replicate it in the larger hardcover format, thus keeping the book to a similar width. It should be slightly slimmer than the recent Father Christmas Letters in the same style.
Exactly it: if we compare the 2023 Father Christmas to the 2012 (or is it 2009…?) hardcover, we get an idea of the general size that Mr Bliss would be in the newer edition.
I’ve known about this for a few weeks (HC email correspondence) though with no date, cover art, ISBN…..that’s why I never posted here.
