This is a rare applied butterfly (Marquetry) box, made by Bohemian master, Ludwig Moser, around 1885. Like typical Moser objects from that epoch, the box is unsigned. But such applied-glass-motif objects were made by Moser and Harrach in Bohemia and Thomas Webb in England (refer to Baldwin's book on Moser glass). Under black-light, the box fluoresces a gentle greenish color, so the glass blank is definitely of Bohemian origin. The box is 3 1/4 inches (8,3 cm) tall and 3 1/2 inches (9 cm) wide. Except for some missing glass-trailing on the antenna of the butterfly (see 3rd picture), the box is in very good condition. It is exceptionally rare to find a Moser glass box with an applied-glass object.
