To mark the 100th anniversary of the company M. Welte & Söhne of Freiburg, the Augustiner Museum published this book, or rather exhibition catalog, 100 Jahre Welte-Mignon (100 Years of Welte-Mignon). The book contains a great deal of detailed information and articles on the work of the Welte company. It probably gives the most comprehensive insight into the Welte company, which in 1904, with a worldwide sensation – the Welte-Mignon cabinet – brought the first reproducing instrument of this quality onto the market.
