Considering you can publish a book on Createspace and have print on demand with zero up front costs, I question the route this guy wanted to go. Sure, in the past the best way to do this was to get the capital together to print a few thousand copies, then sell them out of your garage. If you don't mind storing, shipping, and trying to sell your book the old fashioned way (travel to bookstores and talk to the manager about buying some) it offers the highest profit margin per book sold. However, with Amazon KDP and Createspace, as well as services like Direct2Draft, publishing a book even one with nothing but pictures is easy as hell and costs you nothing up front with a better royalty than any agent or publisher will ever give you. This guy either didn't do his homework or wanted some mega high quality photo printing that you can only get with a monster capital investment and a high quality press (which of course costs a LOT of money and reduces your potential royalties by a lot more).
I never looked at the kickstarter page, but you give me a bunch of pictures and captions and in a matter of hours I could have a book on Amazon that you can buy and have on your doorstep two days later (free shipping with Prime) or downloaded in seconds. This isn't rocket science, and the "indie scene" has changed dramatically in the past few years.
If you have a collection of artwork and you want to see it in an actual book, you can do so for free and for an insanely low price print one or as many as you want, all from your desktop. Createspace, Lulu, and a handful of other services can get you any kind of book you want with zero up front money and even offer it up for international distribution channels.
