We see a lot of "AI" software and websites now which enhance photos and even text, some advanced AI systems have been able to bring to life ancient, unreadable documents which were hundreds/thousands of years old.
Example being – https://www.smithsonianmag.com/smart-news/this-21-year-old-used-ai-to-decipher-text-from-a-scroll-that-hasnt-been-read-in-2000-years-180983084/
I know this is very different from a photo/microfilm image, but I Was thinking, if you could find the exact typeface/font used on official memos from back then, couldn't an AI program then be used to analyse the ramey memo photo and pick out words, heck, even letters to try and confirm what the memo SEEMS to suggest.
