Rene Magritte

Recently we had a discussion with my colleagues about which picture of Rene Magritte is the most known. Which one would you choose?
Meli jsme v praci s kolegy disputaci stran toho, ktery obraz od Magritta je jeho nejznamejsi. Ktery byste volili?

P.S. I chose one which most likely is not the most known :-(. So know I am thinking what is better/worse: to have a special taste (way of thinking) or being simply wrong.
P.S. Napadl me jeden, ktery asi neni uplne nejznamejsi... Takze ted disputuji sam se sebou, zda-li je lepsi mit zvlastni vkus/zpusob uvazovano, nebo proste nemit pravdu.
