After 8 years, however, he decided to go freelance. Having designed fashion, books, cartoons and the title pages for Warren and Marvel's new comic magazines, he then began to work on book covers for several paperback publishing companies.

"I had already been working successfully as an illustrator for a few years, when I discovered fantasy art on an American comic magazine cover. It was a heroic woman fighting a prehistoric monster, and suddenly I knew that this was what I wanted to do. I have always had a special love for the perfect structure of the human body, and fantasy art enabled me to depict muscular and sensuous bodies in all variations in my works. And as I love human bodies, I always try to paint them as beautiful and as perfect as possible".

Nearly all his pictures show scenes of savage and effective sensuality. However, it is not just his choice of subjects that soon made him one of the most popular illustrators of his time, but also his perfect expertise as a painter. Since the end of the seventies alone he has designed more than 300 covers, including "Tarzan", "Conan" and the comic magazine "Heavy Metal". His vivid pictures all bear the signature "Boris".

And Boris is indeed fully aware of the function of his illustrations. "In the bookshops there are always lots of books side by side, and it is often the cover which decides whether a book is bought or not. A successful cover has to attract the potential customer like a magnet." A master of his art, Boris uses his erotic pictures to play on the secret lustful desires of his public like a virtuoso on his violin. But just as he knows exactly what to aim for in his paintings, he is also equally inventive and imaginative in them.
