"....Inside this Violin is the original paper label which reads, “Joseph Guarnerius fects, Cremone anno 1739.” On the right hand side of this label is a Cross over the letters IHS. I found that this Violin is authentic because of the Cross and HIS on the right hand side of the label. Copies of these violins do not have this marking. I guarantee, 100%, plus shipping, that this is an authentic 1739 Guarnerius Violin. "
