Josef Frank was no fan of gamehunting and he designed several rugs with the purpose of replacing real animal skins. His rugs often resembled stone paved terraces or abstract motifs. Flowers and birds were not to be tramped upon, but you could possibly tramp upon on beasts.
The fearsome beast was intended as a counterpart to the ancient Medusa head, which the Romans frequently placed at the entrance of their homes so evil wouldn’t cross the threshold. The rug was designed around 1950 and it has been nicknamed the “Monster rug”.
