I have some good examples of Background Genga (or 
whatever you want to call them) from a show called 
Chuuka Ichiban. These cels all came with matching 
backgrounds and several setup pages, they are 
really neat as far as being able to see the 
process. I scanned some of the Genga drawings, 
including ones of backgrounds with indications of 
where the characters will be, etc. You might like 
to take a look at them! Click on the word Genga to 
see the scans of the drawings:
