Barbara - I sympathise with you re. the washing and packing (been there, done it, got the dirty tee shirt :roll: )
You actually pose a very interesting topic:
If Jobling copied Lalique and Bagley copied Jobling, and Sowerby copied Bagley etc etc did Walther come in at the begining or tailgate at the end?
There was a great deal of plagiarism among the pressed glass makers. Not only were they copying each other, they were also using each others moulds sometimes too. But I think it's not quite as simple as just copying. I personally see it more as a response to public demand and taste. If the style of the moment was, say, all things oriental, then were those who made designs suggestive of, say, peacock feathers copying each other, or were they responding to the stimulus of current style/trends?
What I'm trying to say (probably clumsily) is this: were the glass makers copying each other, or simply coming up with similar responses to common and current style trends? I'll answer my own question - both!
Another thing you mentioned -
I think I must have lead a more sheltered life than you because I didn't know that they made carnival glass, and until recently thought most of their glass was Bagley or Sowerby
Don't worry on this score - most people have no idea that Walther made Carnival Glass. I only discovered it myself about four or five years ago (around the time that I alerted Chris and Siegmar to Walther and Cloud Glass).
They did not make a vast amount of Carnival, but nevertheless it is most interesting to be able to identify items they did make - and in doing so, solve a few mysteries.
