The level of unsteadiness in the hand of whomever 
drew the first of your LU sketches is making me 
worry. If you look as closely as I know I do when 
critiquing my own items, you can see quite a few 
wavers and erase lines on the douga, the drawing 
hand of an amature. Mina, although I am no 
expert, I have a bad feeling you've been sold a 
forgery. 

NOTE: I COULD BE VERY WRONG IN THIS. This is in 
caps because I know I'm about to get flamed a 
lot. I just seriously pondered buying these 
myself because the scene is beautiful. I love LU. 
If real, they would be worth the price but I am 
passing them up based on my own worry. I do not 
believe that it is real, but again I could be 
VERY WRONG. I in no way wish to tarnish Mina's 
reputation, I am simply passing on a 'Caveat 
Emptor'. If you feel they are genuine, then by 
all means buy them and love them. The Last 
Unicorn art is a beautiful thing.

Best,
