Thank you for your appraisal inquiry with Mearto. The item presented appears to be an airbrush painting of a train. The object appears to be signed "Roger Williamson" and dated "1995" to the lower corner. After searching a few databases of listed artist's this name was unfortunately not found. The painting was likely from an amateur artist.
The estimate provided is based on recent auction estimates and results of comparable airbrush paintings by unknown artists, dating to the 1990s. The estimate is contingent on a full condition report. Please note asking or dealer prices may vary. Thank you and please take care.
