Postal Stationery Society

"The introduction of the postcard greatly increased the volume of mail which the PO handled each day, and during the first few years of their use attempts were made to cancel bundles of postcards in one single operation by punching holes through the area of the stamp. Groups of holes shaped into arrows and orbs, and single holes and side clips were experimented with. However, the system attracted numerous complaints about the loss of part of the message area where the card was punched away. In addition, the PO was also concerned that this method gave no indication of the date that the cards passed through the post. In the end the experiment was gradually abandoned, being superseded by other more reliable cancellation methods."
