This is My Land.
This Denis Walter audio cassette tape album was released by J & B Records.
While the precise year is not stated, I am aware that it was produced in the mid to late 1980s.
It was possibly produced for Australia's Bicentennial year in 1988.
As there was no record on the web, I contacted Denis Walter to check the precise year but even he wasn't sure ;-)

The cassette contains 18 tracks (as shown in the photos). 
I combine postage for multiple items.

Questions and offers welcome.
