I have just acquired a rather lovely standing disc paperweight, with a central core of coppery purple, gold inclusions and controlled bubbles, signed
Eickholt 1994 OBU. Can anyone tell me if the initials OBU indicate that it was made by a glassblower under direction of Eickholt at his studio, or does it mean something else?
The Eickholt signature is identical to all other ones I have so far seen in my searches.
Many thanks
