This piece began as a painting which I tore apart into 7 smaller pieces. I then made 7 new paintings which I reassembled.

When I was making this painting I was also taking flying lessons and was studying charts of varying classes of airspace.
This is a map of class B airspace over New York State.
I then made a template of the class B airspace and placed it over the reassembled 7 paintings and shaded the interiors of open spaces.
The shaded paintings were then assembled.
