The material belongs to the final stages of the ecological protests – in 1990 and 1991. The request for international assistance on resolving the environmental problem was one of the ways, sought by the citizens of Ruse in finding a solution to their predicament. Along with numerous petitions to international organizations and media that covered the issue, this bilingual black banner with white-paint letters was one of the most direct expressions of the desire for international help.

The banner was donated by Iskra Pencheva, a participant of the ecological protests, to the Rousse Regional Museum of History in 1991.
