My Grandfather's Cholera Immunization Card from Japanese-Occupied Hong Kong

This is my grandfather's cholera immunization card dated 2 August, 1944. I found this card among his belongings after he passed away in 2007. My grandfather spent the entire Japanese Occupation (and the entire war) living in Hong Kong.
