Color Transplants (2)

Vermeer's Milkmaid in transplanted colors:

Did you guess that the bottom left image is Vermeer's 'real' Milkmaid? A simple survey shows that many people pick another one as the 'real' image. 

 The colors of these Milkmaids have been transplanted from the following pictures:
Portrait of Raden Syarif Bustaman Saleh, by Friedrich Carl Albert Schreuel in 1840
Portrait of Maria Theresia of Austria, by Jean-Etienne Liotard in 1747
Portrait of Isaac de Bruijn, by Jan Veth in 1922
The Milkmaid, by Johannes Vermeer in 1658

Below you can produce your own color transplant with an interactive version of the Milkmaid.
