Big Issue: Shape of the Table

I remember when the US and North Vietnam spent  months negotiating over the shape of the table at which to conduct peace talks in Paris (1968).  It may be an issue for the Kim Jong Un/ Donald Trump talks (i.e., is it strictly bilateral or does South Korea want a representative, and if SK is in, how about China and Japan--one of the papers had a photo of the 6-sided table China constructed for the last time there were negotiations, six-party negotiations.
