The copyrights on these artworks have expired, as is the case with many exceptional artworks. The challenge for a publisher comes in acquiring proper files from which to print, which is why many publications featuring rare artworks are of poor quality. In our case, we are working from an original 1899 folio of the artworks so the image captures- and printing- will be of the highest possible quality. While Mucha was adamant that his publisher at the time not reprint the work, as we understand it the motive was related to his work being appropriated in fragments ad infinitum for commercial purposes. We believe today that 116 years later Mucha would want this most personal work shared with as many people as possible, and in keeping with respect for the depth and breadth of his creation we are publishing this book in a completist and academic manner.
Yes- we're happy to accommodate requests for extra copies of the book! Once the campaign has ended, we'll provide an opportunity to do so within the backer surveys. You tell us how many, we'll send an invoice via PayPal (for those that don't know: Kickstarter does not keep backer credit card information on file for more charges to be made after the close of a campaign), and the extra copies will be sent with your pledge rewards.
