The Friends cast have teamed up for a fundraiser in honour of the late Matthew Perry

Sharing photos of the cast signing the prints, the foundation explained on Instagram: "The cast has teamed up with @soundwaves_art and artist Tim Wakefield for a very special collection of artwork this holiday season.

"Tim has transformed the actual soundwaves of the 'Friends' theme song into these beautiful designs each inspired by a different character, and each cast member has autographed their own small run of artworks.

"And in collaboration with the estate of @mattyperry4 we have produced a very limited edition of artworks embossed with Matthew's official signature.

"All profits will be supporting charities chosen by the cast, including the @MatthewPerryFoundation and their work helping those struggling with the disease of addiction. Link in bio to get one."

The signed prints cost $600, while unsigned ones are being sold for $100.

Shortly after the 54-year-old actor passed away in 2023, Courteney shared a heartfelt tribute, expressing how her on-screen husband "was funny and he was kind".

She said on Instagram: "I am so grateful for every moment I had with you Matty and I miss you every day.

"When you work with someone as closely as I did with Matthew, there are thousands of moments I wish I could share. For now here's one of my favorites.

"To give a little backstory, Chandler and Monica were supposed to have a one night fling in London. But because of the audience's reaction, it became the beginning of their love story.

"In this scene, before we started rolling, he whispered a funny line for me to say.

"He often did things like that. He was funny and he was kind."

And Jennifer remembered Matthew as her "little brother".

She posted a carousel of images and a video clip of her and Matthew on Instagram and wrote in part: "Oh boy this one has cut deep... Having to say goodbye to our Matty has been an insane wave of emotions that I've never experienced before.

"We all experience loss at some point in our lives. Loss of life or loss of love. Being able to really SIT in this grief allows you to feel the moments of joy and gratitude for having loved someone that deep. And we loved him deeply.

"He was such a part of our DNA. We were always the 6 of us. This was a chosen family that forever changed the course of who we were and what our path was going to be.(sic)"
