The Pallas Picture is the only known drawing of Steller's sea cow believed to be from an actual specimen.
It was published by Peter Simon Pallas in his 1840 work Icones ad Zoographia Rosso-Asiatica.
Pallas did not specify a source; Stejneger suggested it may have been one of the original illustrations produced by Friedrich Plenisner, a member of Vitus Bering's crew as a painter and surveyor who drew a figure of a female sea cow on Steller's request.
Most of Plenisner's depictions were lost during transit from Siberia to Saint Petersburg.

Another drawing of Steller's sea cow similar to the Pallas Picture appeared on a 1744 map drawn by Sven Waxell and Sofron Chitrow.
The picture may have also been based upon a specimen, and was published in 1893 by Pekarski.
The map depicted Vitus Bering's route during the Great Northern Expedition, and featured illustrations of Steller's sea cow and Steller's sea lion in the upper-left corner.
The drawing contains some inaccurate features such as the inclusion of eyelids and fingers, leading to doubt that it was drawn from a specimen.

Johann Friedrich von Brandt, director of the Russian Academy of Sciences, had the "Ideal Image" drawn in 1846 based upon the Pallas Picture, and then the "Ideal Picture" in 1868 based upon collected skeletons.
Two other possible drawings of Steller's sea cow were found in 1891 in Waxell's manuscript diary.
There was a map depicting a sea cow, as well as a Steller sea lion and a northern fur seal.
The sea cow was depicted with large eyes, a large head, claw-like hands, exaggerated folds on the body, and a tail fluke in perspective lying horizontally rather than vertically.
The drawing may have been a distorted depiction of a juvenile, as the figure bears a resemblance to a manatee calf.
Another similar image was found by Alexander von Middendorff in 1867 in the library of the Russian Academy of Sciences, and is probably a copy of the Tsarskoye Selo Picture.
