In World War I, all sides used posters as tools to mobilize their populations for the war effort. This poster, published in Vienna in 1918, shows a little girl reaching through a number "8" to deposit a coin into a pile below, an advertisement for the eighth war loan being raised by Austria-Hungary, Germany’s chief ally in the war. The artist who designed the poster was Alfred Offner. Born in Czernowitz in 1879, Offner was a painter and graphic artist who was associated with the Vienna Secession, a group of avant-garde artists formed in 1897 that sought to break with the prevailing conservatism of late 19th-century Austrian art.
