HINTS: (please don't look if you don't need them)
If you need a hint upon #3, then I'll offer two, but you must deduct 2pts from your overall score for reading each one. I'll go ahead and write the hints upside-down just below for those who don't want it.

*ANSWERS*: 1) It's professor Pacôme de Champignac, Fantasio, Spirou, and Panoramix ("Getafix" in English translations) *EDIT*: Oh! I deserve a rap on the knuckles for omitting *Spip the squirrel*, and *Idéfix* ("Dogmatix"), The scoring has been adjusted.

2) Astérix en Corse ("Asterix in Corsica"), the 20th Asterix album

"Corsica" is the best-selling title in the history of the series, owing to its sales in the French-speaking market, but is one of the least-selling titles in the English language. --WP

3) The poster is from the annual comics festival in Ajaaccio, Corsica, an event I just learned about myself! Specifically, this is evidently a piece made by Fabrice Tarrin for the event, which... looks like it was maybe from the 19th show, from 2022?

SCORING:
1) Give yourself 1pt for each character you correctly identified.
2) Give yourself 3pts for identifying the correct tome.
3) Give yourself another 4pts for identifying the -specific- city of the event. (let's give back a near-miss Corsican city 1pt in return, though)

HINTS:
As stated above, deduct two points for each hint taken earlier.

Max score is 11pts 13pts. How did you do?

Btw, this here festival looks PRETTY GREAT!
And look, mateys-- it's coming up again in November...
