Bock Steger Skin model

By Van Leest Antiques

Comments Off

An early Bock-Steger Skin model. It is good condition. After collaborating with Carl Ernst Bock, Franz Josef Steger (1845-1938) also worked with the professor Wilhelm His (1831-1904). Before these collaborations, his earlier models are signed Franz Joseph Steger. The piece is not signed by F.J. Steger; So I believe that the model is made under his collaboration with C. E. Bock.
