Painted on canvas, on an internal wooden frame. Painting size 49x59.5cm (without the external custom frame which was added later in Estonia where the painting is now located.).
Purchased in Beijing in the early 2000s and, if memory serves, from the artist, Lao Dao (born in 1968). The painting here seems of a similar style, and was valued at €1,000-1,500 ($1,139-1,708) in 2018 in Paris. https://www.lot-art.com/auction-lots/Lao-Dao-Li-Zongjun-ne-en-1968-attribue-a/178-lao_dao-23.6.18-fauvepari
Thank you for contacting Mearto. This is a collage/painting by the Mainland Chinese artist Lao Dao.
In the late 90s and early 2000s, Beijing was a center for the arts. China was experiencing an economic boom and the new purchasing power created a market for modern Chinese art. Many artists dealt with the effects of the Cultural Revolution and often used the portrait of Mao as a reference.
Lao Dao 老道 (in English, means ‘old way’) aka Li Zongjun seems to have dropped off the map after the early 2000s. His work seems to span collages like yours and more traditional oil paintings (see link below).
Based on past sales of his work, the Fair Market Value of this painting is between $1200 and $1700.
You may want to try listing it on a Chinese auction site, such as Beijing Poly.
