Dear Anita,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a charcoal drawing on paper with 2 x 2 feet measurements. The painting depicts the portrait of a man wearing a Chinese costume. The drawing is signed by Lu, dated 1950, and located in Shanghai. Sadly no additional information for an artist with this name fitting in style and motif is given by reference books and databases.
Comparable objects were recently offered and sold on the international auction market.
This piece is in good condition and no severe damage is visible in the images provided.
A fair market estimation would be between 30 to 80 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards,
George
