Thank you for submitting your item for appraisal. These appear to be three later prints after Ando Hiroshige ( 1797-1858) from the series Meisho edo hyakkei: one hundred famous views of Edo, e.g. "Ayasegawa kanegafuchi" depicting a man poling a raft on a river. Various impressions of this print are known, these will most likely be 20th century impressions. The prints of Hiroshiges lifetime are more valuable than the estimate given. A hands on examination of the unframed prints by an auction house specializing in japanese prints will be necessary to determin the approximate age.
