Very interesting.
Lost Monkey - I've never heard about anyone else owning the Bonk 3 French "poster" manual; it seems to be a very rare item. To my knowledge, Canadian games usually came with two manuals - one French and one English. Out of the half dozen new Canadian Turbochips I've opened, earlier Turbochips came with full-color versions of each, while later games, like Darkwing Duck, came with the normal English manual and a French poster manual. After opening Darkwing, I assumed all of the Canadian plastic-tray Turbochips were packed the same way. I guess I was wrong
My Bonk 3 poster came with a used copy on ebay. I assumed the owner lost the English manual, but maybe it never came with one, like yours. Anyway, the Bonk 3 Turbochip English manual is well-documented and a lot of us own a copy. I guess the Canadian release just got hosed in the manual department.
Rover - were you living in Canada or where did you get yours?
