Paper back books can be converted into hard back books. Parts of the original cover can be glued onto new cover, if desired.
This paperback book, The Adventures of Huckleberry Finn, was falling apart. I re-glued the pages, re-glued part of the original cover to the front and imprinted the title and author. There is no additional charge to glue a picture onto the cover. I will gladly add a ribbon book mark on request, also for no additional charge.
