Well, I'd mention a price range, but I've
never actually seen another OMG opening cel for
sale.  Thus, I'm not really sure what to price it
at.  Come to think of it, I'm not even sure that
I've ever even seen another OMG opening cel.  
Also, I've had the cel for awhile (it was one 
of my first cels).  So all I can say is that 
it's a very rare cel and just base your offers 
on that fact.  Sorry that I can't be of more 
help.
