Imago is a work in seven parts. The matrix - a thin and light plywood board - is engraved to accommodate a mixture of vinavil and vaseline, which is then imprinted six times on the other white squares. In a critical text of 1997, Ferretti wrote, on Imago: «Elaboration conceived, perhaps the only case, in relation to the space in which the seven works would be found. Uniqueness of the message (or of the referent) and complexity of the solutions in the continuous variation of the identical. The word that becomes an image and in reflection leads back to what is in front of it, to the thought of the beholder ». Imago was exhibited for the first time in 1997, in the Massimo Valsecchi gallery in Milan. The matrix was exposed in the back wall and the six canvases were arranged going from the most legible to those where the word loses its material relief. Since April 2019, Imago has been exhibited on a single wall, in a large gallery on the ground floor of Palazzo Butera.
