Abba has asked fans to pledge 195 pounds to help produce their next official release 'The Official Abba Photo Book' on a crowd-funding website.
The four band members are releasing a limited-edition authorized history of the band's career next April, marking the 40th anniversary of their breakthrough win in the 1974 Eurovision Song Contest, the Independent reported.
The 460-page book has a foreword contributed by each member of Abba and previously unseen photographs.
For 195 pounds, the PledgeMusic, the "direct-to-fan" platform, appeal offers fans the chance to receive a Super Trouper limited edition, restricted to 5,000 copies, which includes an extra section of 20 pages listing all the dedicated fans who have made this limited edition possible.
