After Harris left, there was a period where a lot of experimentation was still going on and there many more accomplished makers arrived. The apprentices were learning and getting better and better.
I believe Joseph Said had a real knack and learned very, very quickly, becoming very good in under the normal 10 years or so of practice it would normally take.
This is the period when Marie and Dobson took on the job of producing "artist" signatures, on pieces that were deemed significant enough.
Fish vases, very tall, attenuated, strapped two-tone bottles, cut-ice lollipops, the cube solifleurs and enormous cylinders.
These were not really run-of-the-mill production tourist pieces.

The dates found on them range roughly between '74 and '82. (I think. I'm open to being corrected. It might be '73 and '79, with the odd anomaly.)
