Hi,
Today we started an open exhibition of WLM pictures on Central Railways Station in Warsaw. Polish Railways have several spots in Poland where the art can be shown for free for public. We managed to put WLM pictures there for 2 weeks. The pictures are placed on stands in B1 poster size in main hall of the station. Each picture has some description + QR-code pointing to the relevant article in Wikipedia.
After 2 weeks the exhibition will be moved to Gdynia and the to Wrocław main railways stations...
The funny thing is that this is 100% free for us.
