Thank you for submitting your item for appraisal. This appears to be a mixed media / oil wash on paper painting by Alexander John DRYSDALE (1870-1934), signed in pencil A J Drysdale and dated 1921. The condition appears to be good and it might be the original frame. The estimate is based on similar paintings offered or sold at auction. "Asking prices" in the trade can be higher and vary. There is no measurement for the sentimental value you might attach to it.
