Wow, nice Queen Serenity!! I agree about 
collecting dougas and gengas. I think they are an 
entirely different experience than anime cels 
themselves. I like being able to see the 
production process in action. I've got several 
sequences of gengas where you can see the 
corrections made, figures omitted, and all sort 
of neat things. 

For the record, I'm personally against separating 
cels and sketches as well as breaking up genga 
sets. I won't buy one or the other even if I pass 
up something I absolutely adore and want.

Below is a genga from Dragonball GT that I would 
never buy as a cel but the genga was just too 
interesting to pass up.

PS: I also just updated my gallery although no 
genga sets (waiting for my Taro order where I 
bought nothing but gengas ^^)
