Last week I had a stamp with Dr Theodor Bilharz, this week I'm staying with medicine for the theme of 'women on stamps', I have two stamps with nurses. The first one was issued by Cuba in 1957 to remember Victoria Bru Sanchez (1876 - 1918), a nurse who died whilst fighting the influenza epidemic of 1918. In 1924 the 3rd of June, the day of her birth, became 'Nurses' Day' in Cuba.
The next stamp is Polish and appears to be connected with nursing and children, though I don't know the specifics.
Thanks for visiting.
Edit: Not to be forgotten Florence Nightingale who made an appearance in the anniversaries set from 1970.
