Also not all reproduction cels has black stamp on 
the green frame.

simple rule to remember, gold seal ON the 
cel=production with authenticity.

Black seal on green frame=official reproduction 
cel.

For FY there are really not that many shots had 
reproduciton cels, it is extremely easy to tell, 
there is probably no more then 30 shots, maybe 20 
or less, of other titles maybe more, but 
definitely not FY.
