Early Pierre Paulin Orange Slice?  

Howdy folks. Scooped up what appears to be a very early example of a Pierre Paulin Orange Slice chair for $100. The base is the powdercoated version and it's covered in what looks like it's original tan leather. The label affixed to the bottom identifies the chair as a Pierre Paulin design but doesn't match the newer versions of the Artifort labels that include the "orange slice" verbiage as a part of the label itself. Do any of you have any information as to how I might better put a date to this particular chair? I've emailed Artifort already and while I'm waiting for a reply from them, figured I'd put it out there to all of you as well.Thanks so much for the time.
