Sperl lived a secluded life in the seventies and eighties and confined himself to his work in his studio. Although he won the Culture Prize of Passau in 1965 and created an almost inconceivable number of pictures he was never widely known. It was only after his death that some of his works were shown in Traunreut in 1987. So, it seems fitting to celebrate his anniversary in this way, hoping that a wider public might come to appreciate his art.

A handful of private owners kindly photographed the pictures of this exhibition and agreed to their publication. They are to illustrate the career of this talented and yet so little known artist, since, apart from the murals hardly any of his pictures are accessible to the public.

We hope a wider audience will come to appreciate and treasure his works.
