Okay, well.. I sent an email to Richard A. Knaack and he got back to me with this (in case anyone else was curious about who exactly painted this work of awesomeness)...
Hi, Keegan
Thanks for your kind words. I was pleased to see the Archive coming, especially with the new artwork. The artist is Wei Wang, I'm told. I know nothing about him, I'm sorry to say except that he is excellent, if this is an example.
That.... Is Incredible!!!
