I have been looking at the Denver Airport murals since the Vanderbilt necklace featured a Quatzal and that creature is prominent in those paintings too.
For those that don't know, there has been a lot of speculation about the airport. It's murals, way out of place and full of symbolism. The pale statue of 'Bluecifer' who killed its creator in an accident. And ofcourse the MASSIVE secret underground facilities under the airport.
The Quatzal returns in multiple paintings. Also notice in the painting where 'war' is defeated, you'll see existing conflicts. India/Pakistan. Israel/Palestine. Balkans (Serbia, Croatia, Bosnia). But also USA and Russia. At the time there was no running conflict? ? Was this a prediction? Also notice that the 'red' of the rainbow starts with the symbolism of the USA/Russia flag. Was this planned ahead?
