Johnny Depp is selling a poem he penned for ex-fiancee Winona Ryder as an NFT for charity

A total of 25% raised from the NFT (non-fungible tokens) auction will go to one or more charities supporting wildlife and the environment, plus an additional donation will be made to a climate conservation fund.

Johnny said in a statement: "I believe ViciNFT is the first NFT company to truly want to protect and enhance the environment.

"I trust the founders of ViciNFT to always put charity and helping others above mere profitability."

ViciNFT is headed up by Bill Gladstone, an author and literary agent, who has represented the likes of Neil Young, Pamela Anderson and Deepak Chopra.

He added: "This is a ground breaking opportunity to recognize creative artists, musicians, authors, poets, and visionary thinkers. Johnny Depp is one of the most multi-talented creative artists of our generation, making him the ideal creative personality to launch creative NTFs for the common good.

"I represent many wonderful authors whose books have raised awareness of important global issues. I anticipate that the success of Johnny Depp's Official NFT series will create opportunities for many authors and artists to help millions of people throughout the world."

Johnny and Winona were engaged for three years between 1990 and 1994.

The pair starred alongside each other in 'Edward Scissorhands' in 1990 and were known for their mutual love of poetry.

The 49-year-old actress - who recently defended her ex-fiance at court after he was accused by ex-wife Amber Heard of physical and verbal abuse - previously said of her romance with the 57-year-old actor: "It was absolutely like nothing before.

"We hung out the whole day… and night, and we’ve been hanging out ever since. I love her more than anything in the whole world.”

The first NFT auction commences at 9am ET today (04.05.21) and ends 5pm ET on May 5, 2021 on OpenSea at the official Johnny Depp auction.
