What are support advertisements for YOUNG POSSE? Difference from Saengil advertisements

Support advertisements are a culture where fans contribute funds (or one person) to display street advertisements for an artist's birthday, anniversary, or live performance. Also known as "Saengil advertisements," from "생일 (saengil)," meaning birthday in Korean, they have become established in Japan, especially among K-Pop fans.

Placing a support advertisement for each YOUNG POSSE member's birthday or their debut anniversary (October 18) is a special form of fan activity that allows TELEPOSSE's passion to be transformed into a tangible part of the city landscape.
