Portrait of Catherine II before a Mirror

Portrait of Catherine II before a Mirror (1762). Vigilius Eriksen.

I found this at Books and Art (link above) where there was this interesting info.

This Danish artist, who worked at the Russian court between 1757 and 1772, produced some 30 portraits of Catherine II with different programs, compositions, and purposes. He was the first in Russia to use this type of portrait with a mirror, making it possible to show the two sides of the subject’s character - the imperious monarch and the sensitive woman.
