Wolfgang Lettl painted the series 13 Attempts to Become a Rooster in 1977/1978. The series can be seen as a surrealist curriculum. At the end of this series there is a self-portrait, not because Lettl liked to see himself or even paint: he just needed to see himself in the mirror every morning to shave; in his more than 60 years of work he has created only six self-portraits, inside with a pictorial work consisting of 500-600 works. The self-portrait with the rooster's beak stems from an interpretation that emerged in this series of works. At the end of the day there is the awareness that it is not important to become a rooster, but rather to demonstrate that you are a Person in the most varied situations of life and this, as can be seen from the example of the rooster, does not always succeed in the best way. . New challenges in life require us to try again and again to treat each other humanly. As humans we are never finished.
