It's a shame there aren't more resources online about Heinz Edelmann, the german designer and illustrator (born in 1934 in Czechoslovakia).
He is a very talented artist who did excellent illustration and design for the mythic Twen magazine in the sixties, worked as chief designer in the Yellow Submarine animation film and created a huge number of posters for Westdeutscher Rundfunk (WDR), book covers for Klett-Cotta and illustrations for Frankfurter Allgemeine Zeitung.
Edelmann has also been a teacher in the Stuttgart Academy of Fine Arts.
Books showcasing his work are hard to come by. However, very recently, Edelmann has published a graphic novel called The Incredible!, where
he refuses to take part in the 21st century. He lives in 1999, indefinitely(...) records bombs dropping and media battles raging, unaware of their political or economic reason, and all in what might have passed for a breezy style circa 1955.He is remembered best, undoubtedly, by his work on the Yellow Submarine, with its quintessential psychedelic imagery, made in a style that has a lot in common with some works done around the same time by Milton Glaser and Seymour Chwast at the Push Pin Studio.
Here is an online exhibition with a selection of his poster designs.
The accompanying image comes from a spanish website where you find a gallery of fantastic creatures drawn by Edelmann.
