I hope i'm not being too critical on your brain
......but it seems to me the card is bleached out.
.....or a chemical/type fade....can you smell the card??? does it smell bad??? ......the other Brain w/ wst is a nice little error.....$100 might be just in the ballpark for both, but i'm not feeling the washed out looking brain card....my spidey senses maybe off, but I hope i'm wrong and your card is a true missing ink, but imho, I highly doubt factory done....
anyway, sometimes you have to take the risk.....and a true gem is found...
I love your focus and you really add a great dimension to this board
Peace
your friend
