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 reproduced in full on its own page, word for word and 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.

The whole case file for this property - 2,031 words, 15 pages, reproduced complete.

Quoted from the National Register nomination for reference 90000240, 15 pages, held by the National Archives in Record Group 79. See the catalogue record.
