Test cel = preproduction cel = part of production 
process/from studio = a lot cheaper than 
production cels but still of reasonable value

If these had been the actual hanken cels, I would 
have expected them to be 5-10 times the price.  
As it is, I think they are a facinating and valid 
part of the cel process, and are as much a part 
of a collection as douga, genga, layouts, and 
storyboards.
