Thank you for submitting your item for appraisal. This appears to be a reproduction or an original copper engraving reproducing a british painting of the 18th century. Even if it is an original copper engraving, the estimate would be rather low, somewhere near the high estimate. It is a very decorative wall art for home decoration, great for anyone who collects marine paintings. The estimate is based on similar engravings by lesser known artists offered or sold at auction.
