The piece I posted yesterday to celebrate the installation of my new glass studio was made by Chuck Simpson in the studio at Inglewood that he operated with his wife Lesley Justin, after Tony Kuepfer moved to Whanganui. It's not dated, but has his full name signature Chuck Simpson. I have another piece, not signed or dated, but again perforated, and I am sure it is Chuck's work.
Chuck of course made a name while he was in New Zealand for the stoush he had over some other perforated pieces with James Mack who was the selector and with the organiser of a national glass exhibition at the Suter Art Gallery in Nelson - but that's another story.
Sadly, both James and Chuck are no longer alive.
