The characteristic style of Fassianos is formed in the early 1960’s. Three main themes remained unchanged during his journey: man, nature, environment. The study of Greek civilization and its involvement with graphic arts and engraving influenced its painting. His first compositions are dominated by the form of the officer with the inflatable, red cheeks, the fanciful squirrels in the outfit and the cartoon-evocative style. Gradually the figures move and acquire their own lives. There are pairs that fill the space as they touch each other, but they remain united in a mass.
