The papers of Mary Church Terrell include a letter of introduction from Haile Selassie, written in Ethiopic script: https://crowd.loc.gov/campaigns/mary-church-terrell-advocate-for-african-americans-and-women/letters-between-friends-all…
I've represented what's on the page as follows, and tagged it "Ethiopic" in the hope that it will attract the attention of someone who knows what they're doing:
[Ethiopian Imperial Coat of Arms]
[9 lines of Ethiopic script]
[signature of Haile Selassie]
Hmmm... apparently there's a free Ethiopic OCR add-on for Microsoft Word, https://www.abyssinica.com/ocr -- I wonder how long I can resist trying to have a go at it myself?
Fascinating! We'll share this page on twitter soon to see if we get any takers. In the meantime, feel free to take a pass at transcription using the plug-in, we'd be curious to hear how it goes. We always look at review as a safety net to let volunteers learn and experiment safely.
Thanks for finding and sharing!
