On Thursday morning, 5th June 2025, a unique event took place at the AO building of the University of Rzeszów: UR Museum Night combined with Children's Day. The programme was packed with attractions for both young and older enthusiasts of history, model making and cardboard art.

The event began with thematic lectures:
- Professor Krzysztof Mroczkowski introduced the topic of airmail,
- Professor Eugeniusz Moczuk discussed the design of cardboard models by early pioneers, analysing changes over time.

Participants then had the opportunity to:

• Visit the exhibition "Paper and Processed",
• View a cardboard model of an airmail aeroplane of the Przemyśl Fortress (presented by Tomasz Król, MA),
• Attend demonstrations of cardboard aeroplane models – prepared by Marek Borka and the Podkarpacka Initiative of Cardboard Object Enthusiasts,
• See NAVIGA Class C ship models presented by Artur Resler – World Champion in ship modelling.

The event concluded with free time for visitors to explore the exhibits further and engage in conversations with model-making enthusiasts. The event wrapped up at 11:00, leaving participants with plenty of inspiration and joy from experiencing a shared passion for history and model making.
