The books are available through the museum's V&A shop at £7.99 each or only £30 for a limited addition boxed set of all four titles.
I know some of you may think this is crazy, but the first thought that popped into my head when I saw this set was how I would love to dismantle the pages and frame the prints as artwork. Each book is 80 pages so at roughly 50 USD for the set that's only 15 cents a print. Now that's what I call affordable art. I can see 6, 8, or 12 of the prints framed and making a big statement. I almost forgot that each book comes with a CD of the prints. If the resolution of the prints is high enough I suppose you could print them out and frame them, then you wouldn't even have to take apart the books. Score!
