In 1984 the City of Prato installed a monographic show devoted to one of the most representative artefacts of the theatre.
Conceived and designed by Valerio Morpurgo, now only of its kind for the vastness of the material and the complexity of the contributions collected, the exhibition documented:
«...the different moments of the figuration and the evolution of his styles until the break with every formal episode (for overcoming of the traditional convention) when the curtain disappears or becomes routine curtain so it hasn’t reason to be an decorative episode.
But, the Curtain, it is not complete died.
Today it is somewhat revalued and the actors and directors recove it in a scenic game, perhaps with elision of that appearance significance more right for the ceremony of the pause and of suspense.»
It was asserted by Morpurgo in ''The Adventure of the Curtain'' - Figurazione e metafora di una macchina teatrale, Ubulibri, 1984, page 12, the catalogue of the show includes writing, between the others by Jean-Louis Barrault, Gillo Dorfles, Francesco Leonetti and Franco Quadri that, as numerous other texs of the milanese publisher, today is a cult for scenografers and theatrical operators, unfortunately it is out of print and unobtainable used too.
