Grand Central Terminal (station) opened on 2/2/1913.
“…It took 10 years to build this sprawling 48-acre hub, at the cost of $2 billion in today’s dollar… It’s been ranked by Travel and Leisure magazine as the world’s sixth-most visited attraction… There are acorns everywhere in the terminal, carved into archways and walls. Because the Vanderbilts had no official family crest, they adopted the acorn as their own, with the motto, “From the little acorn a mighty oak grows.” … Grand Central’s concave 128-floor high ceiling is a view of the heavens from Aquarius to Cancer in an October sky, consisting of 2,500 stars, 59 of them illuminated. But a closer look reveals that the constellations are backward… workers had mistakenly looked at the diagram on the floor and copied it from there, rather than holding diagram up to the ceiling….”
I take exception to that last sentence. Workers lay blueprints out on a table and build according to what they see laid out. Workers do not hold blueprints up as if painting,eg, look at painting (blueprint) look at model to see if the same. That's what artists do. So I think whoever made the blueprint treated it as an artist's painting.
