Ken:
If you haven't seen the design I'm referring to in Ricke's Swedish Glass Factories, could you give me your email address so I can send you a scan of the relevant page (106). Then you can see that the design on Kelli's piece and the design shown in the book are identical apart from the two details I mentioned: the face looking outward rather than upward, and three lines coming from the waist. I have to be honest and say I would be very surprised if anyone other than Lindstrand designed Kelli's piece, although I make no claim about who engraved it.
I'll also admit that this is the second reply I've written. I was a little upset that, although it seems you haven't seen the original design I referenced, you seemed to assume my sole criterion was based on the fact that both designs were based on a nude; that is, if it's a nude, then it's a Lindstrand. Of course I don't believe that. The designs are so alike that, although one (not me) might choose to defend soemone copying them, you could never defend using the term "artistic interpretation" to describe that process.
