The sample book described herein displays the wound glass beads produced during the third quarter of the 19th century by an acclaimed Venetian firm, that of the Giacomuzzi brothers. The book vividly shows what sorts of beads were being marketed by a single firm at this time, and provides much useful information concerning bead sizing systems. Although not marked with the producers name, the folders that accompany the book are of like date and at least one is likely a product of the Giacomuzzis.
