André Saraiva first started graffitiing Mr A. in the 1980s and the character has since been tagged on walls over 300,000 times all over the world. With the artist’s Longchamp collaboration, the smiling face finds a new home on the front of a t-shirt. Featuring the character’s distinctive smiley OX face with the mouth of Mr A is replaced by Longchamp branding. It’s impossible to have too many white graphic t-shirts in your wardrobe, especially when they honor one of the most famous smiley faces in art.
