Thanks, Neil! Yes, born in Philly, now residing in Hatboro. Documents came from a grouping to a vet who lived in Ridley Park, PA.
There is an entire booklet titled German Documents; consists of roughly 20+ pages. Appear to be period copies of documents however as I read through it, I'm wondering if this may have been used for training purposes for Us Military Intelligence school, rather than original documents that required real-time translation.
