The exhibition Ressonâncias: da Voz e dos Ecos (Resonances: of the Voice and the Echoes), by Portuguese painter Graça Morais, is being held at the Champalimaud Centre for the Unknown, in the Portuguese capital, Lisbon, until April 30.

The showcase features more than 100 works by the 69-year old painter. Most of the works belong to collector José Pedro Paço d’Arcos, but the exhibition will also include works never shown before to the public.

Born in the Portuguese northern region of Trás-os-Montes, Ms Morais has a career of more than 40 years as an artist. She has been acclaimed in Portugal and in other countries.

She exhibited more than 30 of her works last year in Macau.
