This extraordinary artist book documents the project “Invisible Oil” by artist Ernst Logar, who focused on exploring the oil industry and its socio-economic influences, with Europe’s “oil capital” Aberdeen as example. The publication reflects on the issue of oil and the socio-political power of the oil industry in detail. It features an oily, black-brown CMYK colour that appears consistently throughout the entire layout of the book in form of monochrome “censoring” surfaces and oil-coloured threads.
