Lora Innes, creator of THE DREAMER, has a post up about fan art based on her characters. Short version: she approves and enjoys it, but she also provides some guidelines. A sample:
▪ YES: Drawing my characters/writing fan fics/makings songs/fan videos, etc for the love it. When this is posted online, adding proper link backs and credits.
▪ NO: Selling prints, advertising space on a fan site, making shirts, buttons or anything else that draws a monetary value.
▪ YES: gifs and memes that celebrate the fandom, with a link back to The Dreamer.
▪ NO: gifs, memes or fan art that does not coincide with the spirit of myself or The Dreamer. (Not limited to but including adult themes, harsh language, hateful/critical/mean spirited subjects. If you wouldn’t see it in my comic, please don’t associate me or my work with it outside my comic.)
THE DREAMER is a webcomic (a print collection is available from IDW) about a 17-year-old contemporary girl who goes back to the Revolutionary War for adventure…in her dreams. It’s easy to see how fans would be attracted to the idea and a lot of what Innes is asking for is just common sense…but also fairly unenforceable. Or, as someone says in the comments:
So much of it seems harmless, I had no idea it was technically copyright infringement. Guess I’ve been breaking the law since I first started making Ghostbusters fan-comics in second grade… ;)
It isn’t just the big guys who have to worry about fan-made prints and so on.
UPDATE: Oops, apologies for misspelling Innes’s name. =(
