A 12X4.5 inch, odd-shaped chord book perfectly designed to fit inthe typical guitar case, this 48-page publication was produced by GuitarWorkshop in 1978.  It boasts more than 560chord shape diagrams. “The chords are grouped by family, so the chords you’relikely to find together in any one piece are next to each other in the book.”  The book is in very good condition with nostains, dirt, or page tears.  Some cover creasesare evident and a few of the chord diagrams have been circled in pencil,otherwise I can spot no additional damage and the stapled spine is tight.  Questions welcome.
