Metron's Mobius Chair comes to us via the
late 1990's Spider Man line's "Madame Web"
figure. I added a piece of cardboard cut in
the shape of a triangle to the chair's backing
(just to shake things up a bit, LOL) and the
circular pattern behind the chair is a print-out
I made. Being red-green color blind it's kinda
hard for me to see the shade differences in
the chair, but I know they all came from
different sources so I'm sure they are
different, LOL! It's not a perfect
comics-accurate version of the chair, but I do
like it!
