Portrait of Frederick II of Prussia
The Portrait of Frederick II of Prussia was the only portrait made of Frederick II of Prussia during his lifetime. It was produced by the German-Danish painter Johann Georg Ziesenis for Frederick's sister Duchess Philippine Charlotte of Brunswick-Wolfenbüttel. He sat for it from 17 to 20 June 1763 at Castle Salzdahlum. On 10 October 2009 the painting, last put on public display in 1937 at the Lower Saxony State Museum, was offered by the Bremer auction house Bolland & Marotz and sold at a price of 670,000 euros. Due to the historical significance of the painting it was registered in the directory of German cultural heritage.[1]
Copies
It is believed that there are two copies which were given to the Duchess (now in the Heidelberg Palatinate Museum) and to George III of the United Kingdom (now in the Royal Collection).
