Alvar aalto 406 question  

Here, let me google that for you.
Google ( http://www.google.com) is really great for questions like this. A search for "aalto 406 leather" produces about 5000 results, the first of which is this online store which sells the chair in leather:

Why thank you
Now why didn't I think of that?!
Let me rephrase; I know it has been re-edited in leather but does anyone know if the Aalto 406 chair was ever originally produced in leather upholstery.

Define "originally produced", please.
The leather chair referenced above is produced by Artek, which was founded by Alvar Aalto in 1935. Is a recently-manufactured Artek chair "original"?
The very first 406 chairs, produced for Artek by Oy Huonekalu-ja Rakennustyotehdas AB, were fabric, not leather. The remaining examples are all in museums. Are those the only "originals"?
I don't know whether Artek started producing the leather version of the chair before Aalto died in 1976. If they did, would those be "originals"?
The company was acquired by Proventus in 1992; are post-1992 chairs less original than the others?
