I hadn't realised that my Belgian-based publisher, BD Must, had run a crowd-funder earlier this year to produce the binder, and as it funded at 225% production went ahead and it's available. Plus I now have a few books to add drawings to for the top-tier funders.
The centre-spread art for the binder is from an early draft of the cover for volume 3, produced for Egmont long before I finished the album, but required for various advance publicity things, so it doesn't quite reflect what eventually appeared in the actual story. It's nice though!
