Robert Irwin shares an adorable Halloween throwback photo from his childhood

Robert Irwin has shared a series of adorable Halloween throwback photos of himself dressed as Peter Pan.

The 18-year-old wildlife warrior posted the photos taken in 2005 when he was just two years old on Instagram on Sunday.

In the photos, a young Robert wore a printed green top with an attached belt, trousers, a green hat and boots while smiling for the camera.

A second image shows him enjoying a chocolate ice cream, while a third shows him sleeping in a pram.

Robert’s post comes after he released a book about his wildlife photography earlier this month.

The conservationist made the announcement on Instagram, calling it an “embodiment of countless years of dedication to the art.”

Robert Irwin’s Australia has arrived,” he captioned a promotional video.

“This is the embodiment of countless years of dedication to the art form of imagery, as well as my deep passion to carry on my father’s important legacy, as I walk my own path,” he added.

Robert said all profits from the book go to conservation.

The first 500 editions are signed by the award-winning photographer himself.

The wildlife warrior later spoke of the book on the Today show, describing it as a celebration of Australia.

“This is a photo book that is a celebration of our country,” Robert told presenters Karl Stefanovic and Sylvia Jeffreys.

‘The great, rugged natural beauty we have here. And the story that photography plays in conservation.’

Photography is a passion for Robert, with the teen saying he wanted to capture spectacular images that tell stories about the natural world.
