First is the book plate for Foundling, actually printed black on brown, done in this scheme because this is the mottle of Boschenberg.
Secondly (and unsurprisingly) is the book plate for Lamplighter, done in the mottle of the Haacobin Empire. The owl is what the lamplighters affectionately refer to as Ol' Barny, the Sagacious Owl that is the sigil of the Haacobins.
The idea is to give to those who are into it a sense of the books actually belonging in the Half-Continent - as coming from there somehow, to add just that little bit more immersion to the experience, to actually make the owning, holding and reading of the book as sensorialy satisfying as possible.
It has so far been a great joy to figure out what plate to do for each book, a challenge which asks me to go deeper into the world than previously. Indeed, I thought I had a lot of information after 30-odd notebooks on their own, but actually writing and designing for the MBT series has me going much further into the Half-Continent than I expected. I can not say I mind either (well, not most days anyway).
Next challenge: Book 3 (Factotum) - I have my thoughts... in fact it was writing this post that gave me an idea...
