My first job (discarding the two months I worked at the corner hardware store at the age of twelve to buy my first electric guitar) was at an Advertising Agency: Norcel Propaganda. From here my gratitude to Norberto Fernández for teaching me the first steps and professional tricks applied to the trade of graphic design.
At that time we used to commission the texts from typography and linotype companies (Letraset was expensive), we used to make a few Photolith films by hand with photopaque, heroic and naïve times, but it was when I learned some fundamental things about the trade.
