Subject: Inviting Students for Book Fair
Our school is organizing a book fair from April 3, 20XX to April 9, 20XX from 9:00 am to 1:00 pm. The fair has been organized to humbly contribute as assistance to the family of the Najafgarh based martyr.
The students have stepped forward to the cause and have donated their books for the cause. I request you to urge students of your school to visit the book fair and buy the books so as to be a part of the great cause.
I am also looking forward to your personal visit to our school to boost the morale of our students.
Thanking you in anticipation,
XYZ Public School
