I've just begun reading this comic as it only arrived today, looks FANTASTIC so far, Francis has spent a lot of time doing this and doing it right, ensuring good consultation with Yolngu and Bininj (in France!), well done bro, I don't see too many people make this sort of effort so people please support this project and get yourself a copy from Francis.
What I like about this is the journey and the exploration involved, leading the reader to culturally relevant information presented in a fun enjoyable way, and with a story to tell. And the illustrations could each be framed as a poster or piece of art in itself! I can imagine kids in school reading this as well as adults, and all didgeridoo players as well.
The comic's website which Francis has already posted on this forum previously but here it is again:
