A Portrait of Ada Dunn Gardner ( née Pigott, d. 1915) seated full length in an Alpine lake landscape with her son Algernon Dunn Gardner (1853-1929) signed lower right 'R. Thorburn / 1856' watercolour on ivory 45 x 33cm Footnote: By her marriage in 1853 to John Dunn Gardner (1811-1908) Ada Pigott as his second wife brought the Dullingham, Lillingstone Dayrell and Denston estates, which ultimately all devolved upon their only child Algernon Dunn Gardner (1853-1929) here represented as a child. Exhibited: London, Royal Academy of Arts, 1856, no. 744 as 'Mrs Dunn Gardner' Condition report: Watercolour on ivory. The support has numerous horizontal cracks, some more severe than others. The painting is poorly supported by the slip and is bowing forward, notably along the top edge. The work is are with wooden backboards. Despite the issue with the ivory supports the paint layers are beautifully worked and appear to be in a very good, original condition. The wooden frame is slightly bowed in places, but the gilded slips are in a good condition. The painting should be examined and unframed by an expert in conservation of ivory supports.
