Has anyone got a copy yet?
Last I heard, they're not due to start shipping until near the end of this month for the first print run, and late July for the second. There were some distributed at the Phoenix Comicon but I passed on the chance to get it there due to the size and weight.
I'd be curious to know if the book contains Peter Ledger's original concept art used by JMS to sell the series.
Not that I know of. Much (most?) of the art from Peter Ledger was published in the B5 script books. Color items were on the back covers and B&W inside.
