What would happen to Liechtenstein if there were no more people? Swiss illustrator Angelo Boog put this hypothetical question to himself. The answer can be found in his three collages which provide the motifs for the new three-part souvenir sheet entitled “Liechtenstein without us” (value CHF 2.00 per stamp). The collages depict buildings, monuments, everyday objects and sections of landscape from the Principality in an imagined future devoid of human beings in twenty, one hundred and five hundred years from now. The disintegration of buildings, objects and cultivated landscape is tangible, nature spreads its tentacles and reclaims its space, numerous new animal species establish habitats. The artist was inspired by American author Alan Weisman who tackled this subject head-on in his book “The World Without Us” published in 2007. To find out what would happen on Earth if humans suddenly vanished, Weisman visited many places around the world and spoke with scientific experts from various disciplines. With the help of biologists, archaeologists, botanists, anthropologists and philosophers he contemplated a world of the future which he describes in detail in his book.
