1833 - age 9
This picture was painted by Andrew Geddes ARA (1783-1844), a cousin of Wilkie's mother Harriet. 
It shows Wilkie on the left, aged about 9, and Charles, aged about 5, on the right. The exact date is unknown. Wilkie is holding an arrow and there was a belief in the Pym family that a small hole on the left of the canvas was caused when Wilkie shot the picture with an arrow because he did not like it. 
The picture was owned by Wilkie and was then sold with the rest of his pictures by Christie, Manson, and Woods on 22 February 1890 . The purchaser was the solicitor Horace Pym, who knew Wilkie, and the picture remained in his family until it was sold at auction for £8000 on 28 June 2001.

Horace Pym's house at Foxwold, Brasted Chart, Westerham,Kent.
