This artifact is the original document that Grandmaster Ip Man used to travel freely between Hong Kong and mainland China.
Back in 1963 Grandmaster borrowed a suit of clothes, as he did not own a western suit, and had his photo taken for this document. This photo is the only photo Ip Man had taken in a suit and tie. You can see in this photo the date issued (March 15th 1963) and the expiry date (March 14th 1968), good for 5 years from the time of issue.
