On the 23 of April the Mexican Post issued a stamp commemorating the Mother's Day.
The modern Mother's Day is celebrated on various days in many parts of the world, most commonly in May or in March/April, as a day to honor mothers and motherhood.
The holiday was imported to Mexico from the USA in 1922, with the newspaper "Excelsior" making a massive promotion campaign that year.
Nowadays the holiday in Mexico is a celebration of mothers and the Virgin Mary. The "Dia de las Madres" is an unofficial holiday held in the country each year on May 10.
