Even though the present logo appeared as early as 1951 in the company graphics and the following year in the printing of price lists, later on it was later represented differently. In one case the F has a trait much more often while keeping the stylized shape. In other cases, the color will change completely according to the graphic needs of the packaging. Sometimes different graphic choices have been tried, as in the '60s, in sporadic attempts to make the logo more in line with the fashions of the time. All attempts were soon abandoned.
