I lost a cel before... but it was a freebie from 
GTO, not something I really cared about. I did 
eventually find it, it somehow got buried in the 
middle of one of my genga sets. I gave that cel 
away to someone else, so I don't have it to 
post. My advice: take a deep breath, and 
carefully take every single item out of your cel 
books one by one and put them back. It might be 
hiding with something.

Good luck!
