In the 1920s and 1930s, mosaics were considered easy to clean and hygienic. The Odorico atelier was often commissioned by wealthy patrons to create magnificent bathrooms, but their washable mosaics were also sited in many public places. A spectacular scheme can be admired by swimmers in the municipal Piscine Saint-Georges in Rennes (1926, still in use) while the crèche Papu (1934, also in Rennes) has a charming railway-theme frieze with steam trains and wagons, station and station master, which runs the length of a corridor. In a classroom there is a playful scene with swans and cygnets at young child's eye level (above). More charming details can be seen in this video.
