In a pair of paintings in the Statens Museum for Kunst, Gijsbrecht demonstrated his inventiveness by combining in a novel way his trompe l'oeil techniques with the vanitas subjects for which he was known. The first one called the "Trompe l'Oeil with trumpet, celestial globe and proclamation by Frederik III" and dated 1670, shows the proclamation of the late King Frederik III spread out on a carpet, with a trumpet lying across the sheet. A celestial globe with the constellations and signs of the zodiac symbolises the world and an open drawer reveals its exotic riches. But there is also a flip side to this celebration of the king and his reign. All the objects are thrown about in disarray - as if cupboards had just been emptied and a clearing out of the late king's treasuries is underway.
