Halfstudio is a Portuguese Lettering and Sign Painting studio established by Mariana Branco and Emanuel Barreira (b.1986) which covers various creative fields always with the Lettering being the central element. Their visual language is characterized by the use of three-dimensional letters and dynamic layouts with striking messages and vibrant colours. In their murals and urban art interventions, the message is always inspired by the community where the piece takes place.

The duo has been showcasing work in exhibitions and urban art festivals both in Portugal and internationally.
