In 1922 I ordered by telephone from a sign factory five paintings in porcelain enamel. I had the factory's color chart before me and I sketched my paintings on graph paper. At the other end of the telephone the factory supervisor had the same kind of paper, divided into squares. He took down the dictated shapes in the correct position. (It was like playing chess by correspondence.) One of the pictures was delivered in three different sizes, so that I could study the subtle differences in the color relations caused by the enlargement and reduction.
This photograph of Prinzregent Luitpold Karl
Joseph Wilhelm Ludwig von Bayern was the first ever photograph successfully
transmitted by wire. This was achieved by Dr Arthur Korn (1870-1945), of the
University of Munich, on 17 October 1906.
