This advertising poster stamp (Cinderella stamp) was probably published between 1912 and 1914 and shows the System Krauss Schwitzbad, or sweating bath, from Germany.

The bath appears to have been designed for domestic use some time around 1910. It may have been an adaptation of the sitzbath with the addition of a cloak to retain the hot air. The heater in the foreground, however, it similar to those used externally with all types of cabinet bath.
