I was wondering if there was licensing requirements for making and selling items with flags of different countries. ?Who would be in charge of that licensing department?
I don't see any TM issues here. In the US, it used to be a problem with, for example, making clothing out of flag material, but that was taken care of by the Supreme Court.
Also, what about making items with pictures of public places like the city skyline. ?Would it be ok as long as you only used pictures that you took yourself with your camera? ?Or would you need permission from the city or state?
No problem if you take the pictures yourself or get rights from whoever did.
