A fertility mask, which is jokingly rumoured to make women pregnant.

A huge collection of Titanic memorabilia. 

And a room full of wide-eyed dolls, enough to give anyone nightmares.

These are just some of the diverse items in Kevin Green's extraordinary collection hidden across multiple sheds and buildings in the town of Donnybrook, 200 kilometres south of Perth.

Mr Green has been collecting bits and pieces since he was a child growing up in WA's Goldfields, where nothing went to waste.

"I was brought up to appreciate old; everything was precious when we were young," he said.

"We'd be going back to Kalgoorlie, and Dad would pull over and say, 'Righto, go and get your pocket money.'

"And we'd run up and down the road picking up beer bottles and cool drink bottles people had thrown out. That's how we earnt our money."

Mr Green says part of the joy of his collection was seeing people's faces as they reminisce.  (ABC South West WA: Pip Waller )

Watches, Coca-Cola and more

Mr Green's personal collection includes West Coast Eagles AFL memorabilia, hundreds of toy cars, a large Coca-Cola collection, and an extensive range of Titanic items purchased from an auction in Boyanup.

With a background in the navy, Mr Green's extensive range of military memorabilia is among his favourites.

"Anything military, I'm just 100 per cent behind," Mr Green said.

"I have a clock, and when it goes off, it just sends a shiver. It plays The Last Post, and it's incredible."

Many items also hold strong ties to regional Western Australia, including old stairs from a hotel in Bunbury, a telephone booth from Karridale and two antique whale spears found beneath the Albany jetty.
