The original 1904 Droste cocoa tin, designed by Jan Misset (1861–1931)
The Droste effect ( Dutch pronunciation: [ˈdrɔstə]) is the effect of a picture recursively appearing within itself, in a place where a similar picture would realistically be expected to appear. In art history, the technique is known as mise en abyme. This produces a loop which in theory could go on forever, but in practice only continues as far as the image's resolution allows.
