Perhaps the coolest character NOT in the final film is this anthropomorphic bottle, whose role was eventually taken by the doorknob. This drawing is signed in the lower left corner, labeled '28' in the lower right.
Apparently the bottle is quite the jolly active fellow, and spills bubbles out of his hat when he takes it off. Again signed in the lower right corner, labeled '29' in the lower right.
