Oh wow that’s a tricky question. I am reading more on the rights of minors to volunteer and appear in media, but this is what I think right now:
I think you know your situation better than anyone else, and you know what’s best for you, even if you’re under 18. I also know that I can’t afford legal defense if your parents sue me. So if you or your parents live in the United States, I’m going to need parental permission. (Just tell me that you talked to them about it, and that you modeling for me is okay. Please don’t lie.) If you can’t get that, for whatever reason, then you can still participate as long as your face isn’t shown in your coloring page and you use a pseudonym.
If we print the book, and you’re still a minor, them I will need written permission for your page to be included. This doesn’t apply to people outside of the US.
(Every person’s situation in terms of guardians/outness is different, so just talk to me about it and we can figure something out.)
this was an interesting question someone asked and I hope I’m handling it right.
