Do you think she is actually signing the checks with her signature or running the stylus on a grooved pattern...

While a stylus and engraved font plate makes sense, I think she is an authorized signature in a district office. Seems improbable 'one' woman could sign 100's of thousands, if not a few million, considering timely book-work, posting, and who knows what else.
The plate displays no obvious machine work other than mounting, and their 'office' is a chainlink cubicle [chainicle?, cageical?], so there were security measures in place.
