These pictorial texts were incredibly confusing. They seem to be designs for various machines, but also at the same time represent various people. This could be a statement on how the war is making people more mechanized. It is dehumanizing the population and likening the population to machines. All the machines that represent the various people have very specific uses and are needed by the population to function, alluding to the fact that after the War, society is going to need its artists to help humanize them again. 

The pictorial text also suggests ideas of loss. It could also demonstrate how many people were lost in the War and so the machine of society is broken and needs to be mended. Each individual person makes up a part of a machine that is vital to society and without these people society remains stagnant. After WWI so many people were lost that the giant cogs of society did not have enough people to power it and so society had to change in order to continue. The giant machine had to change form and it ended up making its parts and individuals change with it.
