This picture has been taken next to the Tec de Monterrey (Ciudad de Mexico), the 14th of February 2015. As you can see on this picture, some people are selling fancy balloons on the street for couples who would like to offer to each other a gift to celebrate the date. Those balloons can be of different size, colors, texts and drawings. In France, this « tradition » is not speicific to one particular day. There is also people selling similar balloons on the street, however there are not only sold for Valentine’s day.
