Some stamps show more than their designers intended. Look at this Serbian stamp upside-down, and in the part formed by the two heads will be seen a third head (as shown in the drawing), supposed to be the death-mask of the murdered King Alexander I.
Then examine the back of the head of Liberty on this stamp from Haiti. The folds of the cloth make the rough outlines of the face of a negress, said to be the features of the President’s wife.
By turning the Prussian stamp upside-down (as it is now) you will see two learned gentlemen taking part in a keen discussion. They are formed by the space on each side of the eagle’s head.
The ghostly Knight of Schellenburg Castle is formed by the left-hand outline of the ruined wall of the 1937 40rp Liechtenstein.
King Neptune, complete with flowing whiskers, appears beside the geyser when this 1938 Icelandic issue is turned upside down. You can see his head in the small dark puff of steam just to the left of the main jet.
The stamp below was the last issue from Austria before the Nazis marched in, in 1938. The design shows a bowl of roses, and the right-hand outline of the largest rose seems to form the head, nose and moustache of Hitler, a case of coming events casting their shadows before.
