Choosing subtle colours, toning down the violent colours which had always been characteristic of his work, Haring takes his inspiration from the colours of the buildings in Pisa and of the town in general, to create a work which would be in harmony with its social and environmental setting. It is one of the very few outdoor public works created by Haring for permanent display. In fact, he spent more time producing it, a full week, than the one or two days it took him to paint most of his other murals. On the first day, working on his own, and without any preparatory sketches, Haring drew the black outline. For the rest of the week, he filled in the outlines assisted by students and craftsmen from the Caparol Center, the suppliers of the acrylic tempera paint, selected because it keeps its colour for a long time.
The mural's title is "Tuttomondo" a word which sums up the artist's constant pursuit of interaction with the public, represented in this case by the yellow figure which is walking or running on the same level as a passer-by. The 30 figures in the mural evoke Haring's typical vitality, and his ceaseless creative energy which allowed him to create and leave behind this anthem to life only a few months before his death from AIDS.
