From the excellent https://www.amazon.com/Mystery-Hanging-Garden-Babylon-Elusiv... :
> [Nebuchadnezzar] celebrated his prowess by inscribing on two rock faces in the Wadi Briza, a ravine in the cedar mountains of Lebanon []. This was the region where the legendary Gilgamesh and Enkidu had fought and killed the monster Humbaba. Nebuchadnezzar referred to it as a place where he had cut down gigantic cedar trees for his temple doors -- implying that he was like Gilgamesh. On the surface of the rock he also had scenes carved that showed himself grasping a tree, presumably intending to cut it down, and fighting a lion, as Gilgamesh had done
That sounds a wee bit circular.
I believe that the reason that it is described as the $1,000 costume is that it features metal supports, which were made from aluminum. During that time period, the process for refining aluminum was extremely expensive, and aluminum was more valuable than gold.
In reality, aluminum became cheap early in 20th century: https://en.wikipedia.org/wiki/Aluminium#Electrolytic_product...
In 1939, massive amounts of aircraft were produced out of aluminum. It's like the authors mistake 1939 for 1839.
Since the authors demonstrate such gaping holes in knowledge that are trivial to check in Wikipedia, this is either complete baloney, or an elaborate prank.
In the latter case, the article is worth reading in search for more easter eggs like that.
