Perhaps the strangest of the many products made to commemorate the Queens Silver Jubilee in 1977 was this vase. It borrows from the Rubin Vase Illusion, devised by the Danish psychologist Edgar Rubin in which we are not sure if we are looking at a vase or at two faces staring at each other.
Here though the illustration becomes a 3D vase featuring the profile of the Queen on one side and Prince Phillip on the other. As you follow the contours around the vase, one profile morphs seamlessly into the other which means the vase is has the strangest asymmetry.
What an object! Where a traditional, decorative object is warped by monarchist narrative using a Gestalt psychology technique. It’s best viewed in this video.
