When this property was proposed for the
National Register, someone wrote the case for it: what the building is,
and why it matters. That document is a federal record in the public domain.
It is quoted below word for word, never summarised. The text was read off the scanned case file by machine, so the
occasional stray character is the recogniser's and the 1970s
typewriter's.
