In the world of antiques, sheet music is classified under the category of "ephemera," which are printed or paper items that were originally expected to have only a short-term usefulness or popularity . Vintage sheet music has two natures. The basic function is to pass along the musical ideas of a composer the actual transcription of a piece or solo. A secondary feature, and the main one for collectors, is the visual impact of the cover. Sheet music is something to be used, yet also a piece of art to be saved and visually enjoyed. The covers offer keen insight into the world as it was, reflecting the passage of time. The memories and history they invoke transcend the music they contain. Lavishly illustrated with over 700 faithful reproductions of sheet music covers.
