Question: I want to sell light up t-shirts.
These t-shirts lights up when you turn them on, in a dark room or when its night time. I want to sell batman,superman light up t-shirts. They are made overseas in China with the batman and superman logo on them. Can I sell them on the streets of New York City and on the web.
Answer: The batman and superman characters are probably copyrighted and perhaps also trademarked. If so, put them on your shirts and selling them would likely be an infringement.
