"Kaninchen und Ente" ("Rabbit and Duck") from the 23 October 1892 issue of Fliegende Blätter

The rabbit–duck illusion is an ambiguous image in which a rabbit or a duck can be seen.[1]

The earliest known version is an unattributed drawing from the 23 October 1892 issue of Fliegende Blätter, a German humour magazine. It was captioned "Welche Thiere gleichen einander am meisten?" ("Which animals are most like each other?"), with "Kaninchen und Ente" ("Rabbit and Duck") written underneath.[2]

The image was made famous by Ludwig Wittgenstein, who included it in his Philosophical Investigations as a means of describing two different ways of seeing: seeing that/seeing as.
