Hey, Petey, who ARE you? Sounds like we've met in Andernach before. Must have.
Yes, Falko, the founder of the Buk-Society, has one. (officially it's a part of our archive, but I guess, since he payed it from his own pocket when starting the society, it's only on loan.)
He bought it directly from Linda then. And, yes, it's as fine as one would imagine from the known photographs.
I once have heared about the number of original copies from the master-head she had done. Think it was a dozen, as mjp stated before. But can ask for the exact number if requested.
