I know that the International category has closed stamp requests. However, I propose to create a stamp for this special day.
International Mother Language Day on February 21 is a day to promote awareness of linguistic and cultural diversity and to promote multilingualism. The day is also a day to remember those brave people in Bangladesh who stood up to protect the language that is a symbol of their culture. I got to know about the day through one of my friends from Bangladesh.
Please read Wikipedia,
"In 1999, UNESCO declared February 21 as International Mother Language Day as a testament to the Bengali language movement and the ethnic and linguistic rights of people around the world."
I believe that one of the purpose of this app is to know and respect each other's culture.
I hope we can share this day with the people of Bangladesh and the world through our stamps.
