Sketchbook spine construction

Abstract

A removable spine for a book having pages bound together by a binder coil includes a base supporting a pair of spaced arms, the base and arms being of a length generally corresponding to a height of the binder book. The base has a width substantially equal to a width of the binder coil, while each of the arms joined together have a distal portion oriented to engage a portion of an outer surface of the book and a proximal portion in a clearance orientation with respect to the binder coil. The spine may be slid over the coil for mounting on the book, and may be easily removed from the book. The arms may be pivotally affixed to the base to allow the book to be opened with the spine in place.
