I have noticed a lot of people will describe one 
of their cels as "most likely" or "probably" 
having a matching background. Why the caution? Is 
it really that rare to find the original matching 
background and is it common to get a wrong/fake 
one with a cel? This just makes me question the 
added value of cels with backgrounds and I wonder 
if there is any way to verify their authenticity.
