1977 Butterfly Silhouettes

5 latticinio twists divide the translucent cobalt-blue ground into panels filled with pink, blue & aqua complex millefiori and pale-blue bundled tubes. Blue/black butterfly silhouettes rest on white roundels with purple sheaths in each of the 5 panels. A 1977 signature/date cane is set near the centre.
5 + 1 faceting. Typical Whitefriars base with a groove between the encasing crystal and the button , which shows some slight roughness from the manufacturing process.
