Illustration by Mark Lang on the cover of The Dons and Mr. Dickens, the fourth in a series of pastiche tales by William J Palmer. This image appears to show Collins around 1850. The picture appears to be loosely based no the Millais portrait of 1850, but is reversed showing Wilkie's parting on the wrong side.
