I think cels from the Three Musketeers are very 
hard to find. I know a collector who cannot find 
any cels from this series, too ... :-(

Cels from Mágical Angel Sweet Mint you can find 
in my gallery 
http://www.frostrubin.com/misc/mi_mint.htm , but 
sorry, they are only to look at, but not for 
sale :-( I got most of them at Yahoo ...
