This portrait type derives from a profile portrait of Edward VI by William Scrots. William Scrots (Flemish, fl.1537-1553) entered royal service as King's Painter in succession to Holbein in 1543. Both Scrots' bust-portrait (1546, oil on panel, 63 x 16¾ in. incl. frame) and his half-length portrait of Edward VI (c. 1546, inscribed 'AETATIS.SVAE.9', oil on panel, 18 x 12¼ in.) at the National Portrait Gallery, London, are believed to derive from an original profile portrait that is now lost (see R. Strong, National Portrait Gallery: Tudor & Jacobean Portraits, London, 1969, p. 93).
