The one below is the actual cover. The other one (sea serpent) was an also ran.

From the brief: The notion that each person is the free author of his thoughts and actions, rests on a cognitive and emotional illusion. The red cover is the final one. The author suggested the idea of somehow using marionette strings and luckily the title had just the right number of letters in each word. Two preliminary ideas are below.

Every designer has at least one old-style/poster type only cover. I guess this is mine.

Just finished the third one in this series.
