My favorite portrait of her, of course, is the 1726 painting by Jonathan Richardson that appears in The Speckled Monster.

Lady Mary in Turkish Dress by Jean-Etienne Liotard, c. 1756
Palace on the Water (Royal Baths Museum), Warsaw
The V&A in London has a miniature of an unknown woman in Turkish dress painted by Gervase Spencer in 1755 that was once thought to be a portrait of Lady Mary, but the museum no longer credits the identification. Still, it’s a beautiful image.
For many years, it was common to identify every painting of a lovely dark haired woman in Turkish dress as “Lady Mary” and be done with it. For example, see this marvelous bit of sleuthing that revealed one “Lady Mary” as a Greek woman named Laura Tarsi.
