Some of you might know of
"The Adventures of Hergé", a cartoon biography by Jose-Louis Bocquet, Jean-Luc Fromental & Stanislas Barthélémy.
Now they are publishing "La Marque Jacobs", a similar work about his collaborator Edgar Pierre Jacobs, who worked on some of the "Tintin" books but is best known for "Blake and Mortimer". It's written by Rodolphe (aka Rodolphe Daniel Jacquette) and drawn by Louis Alloing.
See
here for a preview of the book's opening pages, which includes a scene of little Edgar falling down a well, and writing a dictation: especially well done are the looks on his face as his father warns him not to make too many mistakes or else... the ruler!
Rodolphe's blog includes a scene in which Jacobs is signing copies of the newly-published "Secret of the Swordfish" and a boy asks him if he is actually English. He points out that Blake and Mortimer are English as are Jacobs' shirt and bow-tie. Jacobs finds this flattering.
Other pages, not found on these previews but elsewhere on the net, include his first meeting with Herge and the real-life incident in which they found a suitable model for Professor Tarragon's house in "Seven Crystal Balls", only to hurry off when they realised that it was used by the Gestapo!
