Thank you both! Yes, on the bottom it says limited to 8,000. All seem to have been designed by Paul Hoff, and some have dates of the early 1980's on the bottom. The majority seem to have been made before the merger with Boda.
I had made the assumption that 8,000 is such a large number, to make the limited edition part of it less interesting. Does anyone know then how much they are worth? (Just in case I need to up my contents insurence, she says with more hope than expectation)
And still the question remains: How many different ones were made?
