We are partnering with Österreichische Post AG for the first release of the new Crypto stamp “Vienna – City of Music” – a collectible that bridges centuries of musical tradition with the digital future.

On April 16th, 2026, Qwien becomes the venue for the official release day. From 1 PM, a special post office will be set up on-site where you can purchase the new Crypto stamp. From 6 PM, we will officially welcome our guests for the brand presentation.

Welcome & brand presentation with Patricia Konrath (Blockchain Product Management, Ö. Post AG), Harriet Leischko (Qwien), Marco Schreuder (ESC Exhibition Curator), Michael Luxenberger (District Mayor, Margareten) and Fiona Zacherl (Diversity Management, Ö. Post AG).
