A notable change in Rego's style emerged in 1990, following her appointment as the first Associate Artist of the National Gallery in London, under what was effectively an artist-in-residence scheme. The remit of the Associate Artist is to "make new work that in some way connects to the National Gallery Collection." The National Gallery is overwhelmingly an Old Masters collection and Rego seems to have been pulled back towards a much clearer, or tighter, linear style reminiscent of the highly-wrought drawing technique that she was taught at the Slade. The result was a series of works which came to characterise the popular perception of Rego's style, combining strong clear drawing with depictions of equally strong women in sometimes disturbing situations. Works such as "Crivelli's Garden" have clear links to the paintings by Carlo Crivelli in the National Gallery, but other works made at the time, such as "Joseph's Dream" and "The Fitting", draw from works by Old Masters such as Diego Velázquez, in terms of subject matter and spatial representation.
