Does anyone know what font this is?
some characters seem to be created just for the cover, but i'm quite sure i've seen a very similar font before, but i can't seem to remember what it is.

The most similar font I could find, stylistically, to this (and I don't think it's too close) was Arabolical by Geoffrey Johnston. 'Arabian' choices at MyFonts and FontShop were not even this similar.

On the back of the book it says "Title lettering by Dermot Flynn / Dutch Uncle"
