These stamps were issued to show the pre-payment of mechanical copyright royalties due under various Copyright Acts and General Regulations.

They were first introduced in the UK in July 1912, and had largely faded by the Second World War, although in Australia the continued well into the 1950s.
They were intended to be affixed to the record, pianola roll or cylinder box to show the royalty had been paid.
