'As expected from Genesis, the production values of Mania Days is beyond everyone else's standards. In an inspired stroke that further elevates this beautiful book, many of Gunther's images have been double-exposed and presented as sepia-toned Beatles montages. As with the endpapers, pictures that might otherwise have been overlooked merge to form dreamlike spreads that are every bit as open and impressionistic as the vignettes Derek Taylor used to write; snatches of life preserved as art. Limited to 2500 copies, Mania Days is a gift of a Beatles book. Its contents are as gilt-edged as its gold-leafed pages. Large-format, quarter-bound in leather and housed in a silk-screened slip-case, it's something to treat yourself to and to treasure.
