Harold Briggs claims his Jack Riley Heritage Award winning Snowy Scheme work vanished on Scone Yarns Night on Tuesday, and despite his best efforts, has been unable to locate the one of a kind poem.

Along with two other pieces of literature, it was placed under a coaster while he ordered his meal but disappeared before he returned, and the bush poet is confident it was deliberately taken after going through inside and outside bins with help from staff and not finding a trace.

Mr Briggs spoke to The Advocate about the time and effort he put into writing the piece, and is calling for its return or information, without any threat of persecution.

"The two and a half years it took was to read through a beautiful book on the snowy scheme, over and over and over... to compress that 25 years of building the snowy scheme into something that couldn't be over five minutes took a lot of effort," he said.

There is no copy of the writing, which has been part of his life for 15 years, which makes the loss of it all the harder to handle.

He believes somebody has information about where the prized piece of text has gone, and is urging people to contact the RSL club so they may return it to him.

"I don't want to know who it is, but if you know who it is please just hand it back in," he pleaded.

He is also offering a photocopied and signed version of the prestigious poem if somebody has taken it but would like to keep it in some form.
