Building off of the idea of chrome, here is a literal blast from the past... from San Francisco in 2013. The bare metal aesthetic became synonymous with streamlining in the 1930's. The form is also noticeable for its rotational symmetry, slenderness, and smoothness. And the visible seams make it look interesting. The rocket is cool also.
I posted my favorite photo of this artifact over two years ago, in February 2013. Here. Time flies.
