Thanks for the responses, everyone. I forgot that I already have a copy of Jacobs's
Le Rayon 'U', which I'll read before starting Mortimer and Blake.
BTW, would you say that the style of Jacobs's art changes much from his earlier to his later work? Some of the online images I've seen seem to look a little different - more "clear line" and detailed - than others, but it could be that I haven't seen enough examples to leave an accurate impression.
My French reading skills aren't very advanced, but for that very reason I don't mind the idea of
Mortimer & Blake being a little text-heavy - I need all the practice I can get!
I've looked at
Spirou collections in the bookstore but had no idea where to start - or that it's been around so long! I assume that the
Spirou collections print all the different artists and stories that appeared in the issues of the
Spirou periodical, while things like
Spirou et Fantasio are solo Franquin books?
I don't think Jacobs art changed that much over time, but I should go back and look at them.
Spirou: I have no idea what's in the collections, but it could be the Spirou magazine collections, yes.
I don't think the pre-Franquin issues have ever been reprinted (maybe a few of the Jidehem issues?)
The Spirou and Fantasio series has the following issues (there are also 2 Franquin issues that predate 4 adventures (#1). #1 and #3 are mostly short stories. #2 containts 2 stories that are connected. From then on most of it is 1 story per issue and a few two-parters. Franquin is definitely the best of the artists on Spirou so far; he's one of the great writers/artists in Western European comics.
The other teams definitely have worthwhile content, but none of it (unless you go into the Une Aventure .... par..-series) compares to Franquin's work. I like Tome&Janry a lot. Fournier is good. Nic&Cauvin are not bad, but are hampered by editorial directives. Vehlmann and Yoann (current team) are IMHO pretty good as well. Morvan and Munuera are the weakest by far.
So if you want Franquin's work there are 20 issues of Spirou and Fantasio. His best works are around late 50s/60s period:
