Among the teachings imparted to Uber by his teacher, he prof. Zelindo Bonacini, let's remember this:
paint flowers between one portrait and another. One wonders what relationship there can be between a portrait and flowers? Not Uber, who has always followed this advice, he says that: the painting of zinnias, of the stars, daisies or any other flower, it means for him, for a painter, for a colorist, keep the sense of color alive.”
