I'm soon going to be sending a 14 x 17" cel to 
Japan (from the US).  Aside from massive amounts 
of cardboard and pleas not to bend the package in 
multiple languages written on the sides, any 
suggestions?  And by suggestions I also mean what 
kind of shipping to use too, because so far the 
furthest away I've sent anything is Hawaii, and 
that's still within the USPS regular routes.  

I was also wondering if there was any sort of 
fairly rigid plastic sheets in existance you can 
use as backing on something this big, because 
hey, half way around the world lots of stuff can 
happen to it >.<
