“Landlordism Causes Unemployment”, showing an octopus strangling London (1909)

Landlordism Causes Unemployment
It paralyses the building trade;
It Pauperises the Peasantry;
12 Landlords “own” (?) London, taking £20,000,000 a year;
500 Peers “own” (?) an entire one-third of England;
4,000 Landlords “own” (?) an entire half of England;
The Land Octopus Sucks the Lifeblood of the People.
