There is a company right now who has created 
Archival Plastic containers for Comic Books, They 
are clear, UV proof and run about $3 each. The 
only problem is, the largest size they carry is 
around 10x7". I have emailed them and asked that 
they include larger sizes for cel collectors as 
well. If the people of this board were to email 
this company, they might get the idea that this 
product is something that should be made! The 
address is ht
tp://www.caseenclosed.com/contact.html. You 
can alos check out their products at that site as 
well. They are very interesting, and even include 
materials to mount and display the books on your 
wall. Just a thought.
