Japanese Manhole Cover T-Shirts

Firstly, Japanese manhole cover t-shirts already exist, I found a bunch on Amazon. Why are these different? Why does this need a kickstarter?

The authors of the kickstarter say they are working closely with city officials to use their art, however there is no mention of artist attribution or whether cities will get a portion of the proceeds from selling their art. Is any of that happening at all?

Lastly, the HN poster created an account an hour ago specifically to advertise this Kickstarter project and nothing else. The same Reddit user has been spamming that platform with the project (https://www.reddit.com/user/aquintar).

To me, it just looks like two white guys are stealing Japanese art and putting it on t-shirts. Good for them, but leave HN out of it.
