A monograph on the work of the still largely undocumented career of the Flemish still-life painter. The author misunderstood the Rijksbureau voor Kunsthistorische Documentatie's (RKD) abbreviation system on photographs of works in their photo collection. The RKD writes "UBI" on the photo when its location is unknown, but Decoteau understood this to mean that there was an anonymous "Ubimaster" working in Clara Peeters' style. See Peter Sutton, "IFAR Journal", Vol. 8, Nos. 3-4 (2006) p. 35.
