I had the pleasure to illustrate the recently published version of the text book "Green Line - Oberstufe", for English secondary school students.
The German publishing house Ernst Klett Verlag has this collection of books in their program already for years and they update regularly its content and its design. For both areas I had excellent contact persons, with a good eye for reduced and stylish graphic and a dedicated interest for highly topical issues in the English speaking countries all over the world.
It was a real pleasure and I hope it is not the last time I will collaborate with my Klett editor. You can see some of the illustrations in my other webpage.
