A note from the provisional gobierno of Mexico. I’d provide a clearer scan, but the money actually looks like this – it’s weathered and faded and battered and worn, but it still has enough self-respect to resist flying apart when you tug on the ends. Note the dollar sign in the big “20” – shouldn’t they have a P, or something? Perhaps, but the Mexican money uses the dollar sign for pesos.

That’s the Mexican coat of arms in the middle of the lake.
