starting a wall mural with my son

The completed mural will consist of 54 pages: 9 high by 6 wide.  We have started by drawing the upper two-by-two pages.  In the middle is a small scale depiction of what we want the large picture to look like.

I hope we can both learn a little about scale and coloring in this project.  If we add a few pages each day, we could 'finish' in a month.  By then, we might be skilled enough to redo the first few pages.
