The CNP Logo is a play on Rosebud, the famous sled in the movie Citizen Kane. The sled was used by director Orson Wells to represent Kane’s most valuable material possession.
From Wikipedia: “The Rosebud sled was the small amount of love given by his weak, abused mother – which brought him joy in his desolate painful childhood and at times helped to protect him. Most humans about to die – recall the most important, valuable things in their lives: for Kane, the Rosebud sled was the toy that represented his valuable joy and remembrance of love. ”
