I am also a fan of the little prince.
You are only allowed to use material you own the copyrights of! This is clearly stated in the briefing.
This idea can not be realized by Victorinox as it is at the moment.
Hi Dora, thx. for your information. But the illustrations of little prince are free..and in this version it's drawn by my own!
fyi: in 2014 the rights/copyright for the book "the little prince" will be completed.
so, for the moment: " what is essential is invisible to the eye." :-)
thx. for your voting! shalom!
