I think the reason why I love art deco so much is because it it represents modernism mixed in with inspirations from all of history only taking the best parts.
It also revels in the idea of glamor beauty an exceptionalism while also keeping everything practical and easy to use.
I still feel like we don't have any style that even comes close to this.
I also feel like this was the ultimate expression of pure Americana because it was inspired from all around the world but permanently featured in the USA even though it originated from France.
