A big thanks to Timo who directed me to these two Spirou pages drawn by Daan Jippes under the name Danier, written by him and Yann and translated into french by Etienne.
Daan: This is really wonderful tribute!
Maybe a longer Spirou story some day ?
Until then I'm looking forward to a second Havank album. :)
And don't forget to check out Daans first Havank album. Some samples can be found if you use the Labels function. (Just click on Daans name below.) Just did that myself and realized that I had missed one comment from Daan regarding one of his childhood drawings.
Daan: I got the Chlorophylle scan +several others from a guy who had purchased some of your early sketchbooks. (Can't remember who it was who sent them to me. It was many years ago.)
Update July 2012:

[Edit: Please see the comments for Jippes "story behind the story" about these pages.]
