Announced by the USPS on January 11th:Filled with passion, rhythm and stories of life, love and loss, mariachi music is an integral element of Mexican American culture that has become deeply rooted in the United States and has fans around the world. Each of the five vibrant stamps in this pane of 20 features a musician dressed in a traje de charro, the traditional outfit of mariachi performers, playing one of five iconic mariachi instruments: guitar, guitarrón, vihuela, violin and trumpet. Rafael López designed the stamps and created the art. Derry Noyes was the art director.

Mariachi stamps celebrate the unique traditional music of Mexico that has become deeply rooted in the United States. Each of the five new stamps in this pane of 20 features a musician, dressed in traje de charro, the traditional outfit of mariachi performers, playing one of five iconic mariachi instruments: guitar, guitarrón, vihuela, violin, and trumpet. The geometric shapes in the background of each stamp are a nod to Mexican villages, where mariachi music originated. Rafael López designed the stamps and created the art. Derry Noyes served as art director for the project.
