What would you bring on a deserted island ?

I have to bring 3 things for an art project and it would be 3 things that I would bring if I was on a deserted island . I thought of matches to make fire but I can’t think of the 2 others . It also has to be quiet small as we r going to put it in a printer and print the pictures off Thanks


A sat phone so I could call for rescue.


The autobiography of a Yogi by Paramahansa Yogananda was the book loved by Steve Jobs maybe it's an idea a pot with fire would be ideal
