I don't see a Mishima "genga character design 
sketch" on either Mandarake or AMuseum. But if 
they're not posted to the sites, how do you know 
they even have them?

Mandarake and AMuseum both sell consignment 
sketches, so maybe they were both asked to 
promote the same item.

Or maybe you're just seeing things that the rest 
of us aren't seeing.
