(e.g., digital assets, models, or stamps).

I couldn’t find any official or widely documented references to a project or series specifically titled "LS Ukrainian (Gentle) Angels Sets 34-50."

In Ukraine, the term is most commonly associated with Angel’s Day (Name Day), a traditional religious celebration of a person's patron saint. There are also various cultural and humanitarian projects using "Angel" as a motif to honor children or volunteers, but none that match your specific numbering.

(e.g., a social media group, a specific website, or an auction catalog).
