I started in the late 80s, so I have been 
collecting cels for over 10 years now.  During 
the early days, cels are dirt-cheap.  I'm amazed 
seeing some of these cels gone up in crazy 
prices.  For example, a Dragonball Z cel with 
background is used to be for $5 in Japan, now it 
worths for $500 in the US...amazing.
