The Cave of Mayrières supérieure (, ) is an archaeological site near Bruniquel, Tarn-et-Garonne, France, which contained two prehistoric cave paintings of bison until they were erased during an attempt to remove modern graffiti by members of the Eclaireurs de France, a French scouting association. The act earned them the 1992 Ig Nobel Prize in Archaeology. References External links Paintings before removal Landforms of Tarn-et-Garonne Mayrieres superieure Archaeological sites in France
