The banner was created thanks to the generosity of the members of the Association, employees of the largest industrial plant in Solec at that time. It was designed by Józef Lewandowski and made by the Poor Clares Sisters from Bydgoszcz. Work on the banner was interrupted by the introduction of martial law. After the revival of Solidarity, the banner was completed in 1989. In 2019, it was donated to the Museum of Solec by Independent Self-Governing Trade Union "Solidarity" Region Bydgoszcz, Branch in Solec Kujawski.
