Handstamp Cinderella Stamp
Any postal marking stamped by hand, whether as a cancellation, routing mark, or other processing notice — such as "Returned to Sender" and "Postage Due." Various handstamps appeared frequently on mail a hundred years ago, and postal historians delight in the stories they tell. Handstamps are less common today, replaced in many instances by labels or automated printing.
