to set the context
I had come across the Ellen's bill board 24 Aug. It was blank. I drew on it the image of the mountain. Returned on the 27th, it had been blanked out. I redrew. Blanked again 2 days later. Redrew. Discovered the bill board had been blacked out 31st. Soon the Mountain re emerged white in a night sky. Found blacked out again at dawn, 4 Sept. Mountain re emerged by early morning. What happens next?
Below, # 1 thru 10 illustrate the context and technique of the drawing by Ellen's.
