Sofia Advertising Company has assisted PLENA Bulgaria's participation in various events: fairs, exhibitions, seminars, etc.
It's worth mentioning the assistance of the Agency when PLENA Bulgaria supported the realization of the European Architectural Awards for Bulgarian Architecture – VIZAR. The participation of students from the National Academy of Arts in the creation of the sculpture "The Egg" was also impressive. At the bottom was the sponsor's idea and the material came from the quarries of the company near the town of Slivnitsa.
