“The collecting truck is back!”, poster calling for collections of “gifts of love”, 1915

The sending of parcels from the home front to the front line was permitted from 10 August 1914, but had to be suspended for the first time by the beginning of September 1914 because the system was unable to cope with the volume of parcels being dispatched.
 

The poster had been used as a medium of communication for commercial purposes well before the First World War, and advertising art had already become established as a separate branch of art production. With the advent of war the poster became a modern vehicle of political content.
