Image: The front, back and side of the Dumas Viola by Giovanni Paolo Maggini. From Gio: Paolo Maggini: His Life and Work, Margaret L.Huggins (1892). The authors assert that: "As a specimen of Maggini's violas the Dumas instrument may confidently be pronounced unsurpassable. It will bear comparison with the finest violas of the other great makers."
