1925-6 Dunedin Exhibition souvenir token

Dunedin, in New Zealand's South Island, played host to the 1925-6 New Zealand & South Seas International Exhibition.

Along with many other manufacturers showing their wares, The Gramophone Co issued a souvenir.  
This was a replica record, 32mm across (1¼" - the same size as a penny).
Made of aluminium, and painted black to resemble shellac, it was inscribed on one side as follows:

HIS MASTER'S VOICE
INSTRUMENTS & RECORDS
in the middle, between the words INTERNATIONAL EXHIBITION.

Around the outside was
NEW ZEALAND & SOUTH SEAS DUNEDIN 1925-26.

On the reverse it was inscribed with concentric rings to resemble a record's grooves, with the 'label' being the famous Nipper logo above the words HIS MASTER'S VOICE.

It is thought the tokens were sold for 1d each.

It is possible that similar items were issued for a contemporary exhibition held in Johannesburg.
