Eragon’s Guide to Alagaesia, the book illustrated by Fred Gambino and Ian Miller, amongst others, has a related video on Amazon, with someone’s hands turning the pages and exploring the novelty flaps.
I gather that the book has been a huge success but one of the illustrations which Fred produced was actually left out. In my view it was one of the best ones and it showed Ellesmera in the winter. As above. Anyone interested in buying a print of this one should let me know.
