Authentic Signed WWII Japanese Rising Sun Flag

Authentic World War II Japanese silk Rising Sun flag that was recovered from the Imperial Palace in Japan during World War II. It measures 29" x 41" and overall is in good condition. There are a few small snags to the silk, but no rips or tears. Some light staining but nothing major. Both leather corners are intact but only one string is remaining. The writing is crisp and clear but we don't know its translation. Attached to the flag in the upper left corner are three campaign pins that are also included.
