My favorite Blade Runner art outside of the John Alvin one-sheet is the Tyler Stout. I do have the Astor version, and that one is my preference over the Kako. But, maybe I am biased.
The detail on the Kako print is amazing, especially the eye with the Tyrell Corporation text. However, composition of the print with the huge title block taking up 2/3 of the space just ruins it for me.
Also, this is essentially the second release of the same artwork from 2008 with little changes. Given a choice, I would rather have the original version.
