The other day - thanks to
@Matteo (and his parents) - these arrived on my doorstep and made me a very happy camper:
One of them contained a reprint of a Tuniques Bleues book.
Coincidentally, the next day, an eBay purchase of Spirou Album 277 turned up (missing several pages but that's an occasional annoyance I have had to learned to live with). The albums are hardbacks which contain 10 or so of the weekly comic bound together. This one contained part of the serialised version of the same Tuniques Bleues story.
Kind of. What they actually published for the weekly serial were the lettered pencils - with notes from the author and artist underneath the pages. This is the sort of thing American comic book readers can only hope that Fantagraphics Press will get round to doing one day (and then in limited runs of insanely expensive hardbacks).
