Dear Giovanni,

Thank you for contacting Mearto with your appraisal inquiry. The presented object is a drawing in ink and watercolor on paper with the measurements of 70 x 60 cm. The drawing depicts a view into a forest and is signed "Roy Jackson", dated "12/88" and titled with a pencil in the right corner "River, rocks e tree". Roy JACKSON (1944-2013) is famous for abstract motifs but there are some works with motifs like this secured.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 400 to 800 AUD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With kind regards,
Georg
