The soundtrack of the popular Dinamo song "The streets are blue all the way to Maksimir" symbolically and effectively aligns with its message to the joint birthday celebration of two Zagreb symbols. Dinamo and ZET have completed a full 115 years of existence, 11 and a half decades of love and pride... GNK Dinamo will mark its 115th birthday on Sunday, April 26th, and ZET fits perfectly into this story, having already stepped into its 115th year at the end of last year since the electric tram was introduced in Zagreb. These details alone were enough for two Zagreb symbols to unite in joint celebration.

Dinamo's "Nema predaje" Foundation and the club itself, in collaboration with ZET, presented on Saturday at the small roundabout in front of the entrance to Maksimir Park a specially decorated Zagreb tram that is visually themed and dedicated to Dinamo's birthday.

– I don't know how to express how happy I am that we're working together, both Dinamo and ZET, because there are so many connections between these Zagreb symbols. Really big thanks to everyone at ZET for expressing their willingness to help us celebrate our birthday, for jointly marking 115 years of Dinamo, but also 115 years since the introduction of the electric tram into service in Zagreb. In addition to this campaign, we also organized ZET's brass band which delighted citizens with their performance on Ban Jelačić Square and then along Gajeva Street all the way to Cvjetni Square. This was followed by socializing with supporters in Španski in a campaign called "Dinamovo" – highlighted Dinamo Supervisory Board member and "Nema predaje" Foundation manager, Saša Pavličić-Bekić.

ZET Board Chairman Marko Bogdanović also addressed the gathering with an emotional speech:

– Allow me to express my exceptional satisfaction at being here. The coincidence between these two Zagreb institutions is incredible. Here we have Dinamo celebrating its 115th birthday, and we have already marked 115 years since the electric tram was introduced in Zagreb. There are several more connections, these facts fascinate me... We're also connected by the yellow color, the club used it in various ways back in the Građanski era and later in more recent history, and Zagreb trams were yellow until 1923 when they adopted the blue color. ZET was also connected to the club in football terms both in the Građanski era and later. In the first days after the war, Dinamo used ZET's pitch, for example, and played their third post-war match in borrowed ZET jerseys. In any case, I thank Dinamo and the "Nema predaje" Foundation for this invitation. It all started at the beginning of the year when the initiative was launched by Saša Pavličić-Bekić, and then we began developing the idea to jointly celebrate 115 years. Of course, there's also the commendable donation from the Foundation intended for a child with special needs whose parents are long-time ZET employees. I would like to take this opportunity to wish Dinamo luck in Sunday's match, and also wish all the best in future endeavors, many more beautiful and successful years for both Dinamo and ZET. Just in the style of the slogan on the tram itself – "we ride through the history, but also the future of Zagreb together" – added Bogdanović.
