Wikipedia Overview
A duplex canceller was a hand stamp used to cancel postage stamps and imprint a dated postmark applied simultaneously with the one device. The device had a steel die, generally circular, which printed the location of the cancel, together with the time and date of cancel. This die was held in place by a handle with an obliteration marker, often oval shaped, off to the right side that was applied over the postage stamp to prevent its reuse. The ink came from an ink pad.
