This elegant little art book is a never-before-published treasure written and illustrated by Yoko Ono in 1952, when she was 19 years old, at the advent of her artistic career. Featuring whimsical hand-drawn text and minimalist drawings in chalk pastel, this sweet story tells of an invisible beauty that we all know, but cannot see. But there is one person who can see it: 'Smelty John.' Written years before Yoko met her famous soul mate, Invisible Flower offers a glimpse into the early process of a brilliant conceptual artist and eerily heralds her relationship with one of pop music's most beloved talents. Sean Lennon discovered this little jewel in his mothers' archives and will contribute an introduction, and Yoko Ono will contextualise her work in a new afterword.
