Ghost of a Genius by Paul Klee in the year 1922. This work may be a self-portrait. Klee had very large eyes, a domed head and a closely cropped beard. The artist made many puppets for his son, and this figure, with its arms flopping down and tilted head, appears to have been inspired by a puppet. The figure was created by a process of oil transfer, rather like making a carbon copy. The artist used a sharp instrument to draw the outline of the figure on a sheet painted with special oil paint on the underside. The black smudges show where Klee's hand rested on the paper.
