A lady with a mask tuning a guitar

The composition derives from Honthorst's painting in Lvov Picture Gallery, Lemberg, which is dated to circa 1623 (see J.R. Judson and R.E.O. Ekkart, Gerrit van Honthorst, 1999, p.175, no. 219, fig. 115). The Lvov picture is accompanied by a pendant, depicting a viola da gamba player (op. cit., fig 116).
