1765 or 1761 Queen Charlotte, when Princess Sophie Charlotte of Mecklenburg-Strelitz by Johann Georg Ziesenis (Royal Collection)
Mario asked who painted this so I went through the Internet and through the UK Royal Collection to find out who painted it. It turns out that this portrait is listed on the last page, page 125, of the UK Royal Collection. So the artist's name, date, and location were added in response to Mario's question. Posted to Royal
