CEramique RENéNEveux. If you say this phonetically in French it is CRN. This studio opened in 1944 and its owner Charles René Neveux employed up to 50 staff, including some 15 decorators between 1949 and 1959. They produced a wide range of work from utilitarian goods including jars, to special commissions for international clients. Due to ill health the company was taken over in 1959. Pieces signed by Neveux himself are fairly rare.
