His painting "The Reverse of a Framed Painting" (1670, Statens Museum for Kunst) is one of his most original contributions to the trompe-l'œil genre. It is a deceptively sculptural representation of the back of a canvas frame with the small nails fixing the canvas in the frame and a small slip of paper with an inventory number. The painting itself is unframed. The painting was displayed leaning against a wall in the entrance hall to the Royal Danish Kunstkammer thus increasing its illusionistic impact. Today, the painting is exhibited standing on the floor against the wall thus creating the idea that the painting is waiting to be hung up.
