Some very minor movements to joints, however structure generally firm. Cream stain and blue paint to timber is original to the piece. Very minor age separation hairline to the seat panel, as is common to these examples, and not affecting overall appearance. Underside signed and dated 1960 by cabinetmaker van de Groenekan, and additionally later branded with Groenekan’s HGM mark..
