Paragon Cafe - Cheque.
As Kytherian shop keepers became more affluent in the period after WWII, they began to make displays of this new found affluence.
This is reflected in the ornate Art Deco re-furbishment of many of the shops and shop fixtures - but is also manifest in simple things - such as the elaborate and artistic designs of business and Company cheques, for example.
This is cheque from the famous Paragon Cafe in Katooomba, NSW. [There are multiple entries for the Paragon Cafe in this, and other sections of kythera-family.]
Note that, £1,498.00.00 would have been considered a substantial sum of money at the time.
