With MacGregor’s Vegetable Stall, comparison between the painting and the x-radiograph shows quite clearly the changes the artist has made.

Perhaps the most striking is the painting out of the female figure: an almost life-sized, perhaps fully-realised figure study to the right hand side, sitting counting her takings.

It is not entirely clear from the x-ray just how finished the figure was before she was painted out, but we can clearly see the other changes the artist has made in order to cover her up.

For example the knife on the table and the bunch of leeks at the bottom right cover the figure’s body. Also, quite dramatically, the artist has transferred and reversed the entire wooden framework supporting the onions from the opposite side of the painting to cover the area where the figure’s head was.
