The virtual visit is one of the programmes of a physics competition's final called Mikola Sándor National Physics Competition. This is a national physics competition for 15 years old sudents, in which 3-4 thousand children participate. In the final, 50 students, who were the best in the previous rounds, take part. The audience of the virtual visit is made up of them and their teachers. I attached the crest of the grammar school which holds the final.
I would like to ask a poster like the one which is shown in your email. The place of the event should be "Gyöngyösi Berze Nagy Gimnázium" ,which is the official name of the grammar school.
