H is for House.  An archetypal house can be made with a rectangle, a large triangle forms a roof.  A small square makes a window and a small rectangle mades a door.    

Rhoda Kellogg is a celebrated expert in children’s art.  Below is a diagram she compiled of themes from children’s drawing’s from around the world.  Note that children around the world draw a house in this archetypal form.  I find it absolutely fascinating.
