Our Classic books are "perfect-bound", similar to a paperback book. Perfect binding is a thermally-activated technology that binds the cover and pages together at the spine with a strong flexible glue.
Our Flush Mount books are also bound by hand and lay completely flat when opened. The binding is a little different from the Prestige books. The Flush Mount albums are bound on the edge of each page so there is no gutter, making the pages look almost like an accordion.
