Among my favourite comics (although I hesitate to use that word, it doesn’t convey how beautiful this work is) I now have to count the free online one Bird and Moon. It’s a poetic cartoon/picture series about birds.
When you’ve read it (you should) check out her (the artist: Rosemary Mosco) other works as well. Especially “Parts of the bird” and “Ruffed grouse love“. The latter is exactly what I’ve always imagined that birds really sing to each other, well, that and in the case of the small songbirds outside my window in the spring “central apartment, two bedrooms, close to public transits!” in a typical newspaper style
