So i am an artist that is under 18 but I’ve garnered some fans from the art I produced and I want to start selling my art and producing stickers, keychains, etc at conventions. but i see that most conventions require you to be 18 or older to run an artist alley booth. is it possible for my guardian to sign up for me or will that be considered proxy selling…or is there any conventions that allow minors to host a booth?please help!!!
