Haven't been following as closely since mid-Jan.
Was the 'keystone' ever worked out?
My 15yo is doing her history homework, and had to analyse a cartoon from 1918 by Ravenhill. It's about the League of Nations post WW1 -there is a sign in cartoon saying 'League of Nations Bridge'.
The keystone is not in the bridge; the bridge is being held together by a bit of metal.
A block with 'keystone USA' written on it is on the other side being leaned upon by Uncle Sam.
It leapt out at me.
I can't post a pic…won't let me. Anyone else?
