I really thought about that for a while, and I think it´s a mix of appreciation and getting some kind of closer to the fame of the bigger ones. It´s interesting, because there are a lot of other free walls around that place. But they all go in someway around that house, they want to make a piece close to the house. Interesting. For me it is just a magnificent phenomenon and I just can spend my whole time with that. ... what I actually do... :-) There is going to coming a very nice book about the start of graffiti in Frankfurt city from the 80s when it started to the 90s. This will be part one, and they are doing more for each decade. Some close friends are doing that and they are before finishing, it should be published around march next year. I will send you links by then. The guys who are doing that, and who have been involved in some of the artworks I posted, are from Naxos and Mainstyle. I always write "friends". Because not everybody wants to be mentioned or be in public. But Mainstyle wants to, they do the book, and I can really recommed as well to check out the website. There are some fantastic train collections and just meanwhile historic material with old but good graffiti stuff from 30 years ago (everything is from Frankfurt and region): https://www.mainstyle.org/
