Anna Leopoldovna, born as Elisabeth Katharina Christine von Mecklenburg-Schwerin and also known as Anna Carlovna, was regent of Russia for a few months in 1740 and 1741 during the minority of her infant son Emperor Ivan VI.  The biographical caption in English on the reverse of the card doesn’t say where the painting is located.  The card has three stamps and a large, full postmark.  Lower left corner has a bit of postal bumping.  (She gets her own postcard!)  Grade: 2
