Got my Parco Gray-Haired Obi-Wan as well, though I haven't freed him from his plastic prison yet. Not as different from the regular release as I had hoped, but a must have for me. This is one of my favorite Kenner vintage variations.
This was a must-have for me too, but I did have a minor gripe: For some reason, they used a shade of grey for the hair that's almost the exact value/tone as his skin color. It makes his facial hair and eyebrows invisible! They accurately show this on the card art Ben, so I guess it's intentional. What's odd is that the whites of the figures eyes are also grey, leading me to believe that they haphazardly switched white to grey on some template and forgot about the eyes
