Large, low-domed studio glass swirl design with a signature near the pontil. It measures 8.5 cm diameter and stands 5.2 cm high with a design of multi-coloured swirls. It has a roughly finished/snapped off pontil and a signature which I think reads ? Millar near the base. It is in very good condition, there is a slight ripple at the top surface of the dome which is not unusual in studio glass.
