Eames Shell Chair Mold

I was thinking chairs this morning and remembered this photo. I did not have my camera handy at the time so the photo is from my colleague's iPhone. I was at The Henry Ford a year or two ago and ran across this baby. I'm in manufacturing (not furniture) so I geek out about how things are made and cool tools. This is (one of?) the original molds for the Eames shell chair. Of course a few examples of the chairs are seen in the background. I have a replica Fiberform Tulip chair I plan to restore that I saved from the trash. I need to learn a bit more about the chairs and the Saarinen/Eames relationship. Heck, the upper part of the chair may have been the same. Oddly enough, I cannot find a photo of a Shell and Tulip side by side. Perhaps it's a Batman and Bruce Wayne situation.  I've said too much.
