I've recently produced a set of posters based on back to the future, the designs are quite unique and have become a kind of signature style (you can see a sample here dave will design - a freelance graphic designer based in Liverpool: Back to the Future 3 Poster: Coming Soon) However, recently I've noticed a Canadian designer who has only just started selling posters based on the same idea as me. She has also produced a back to the future poster, and since then has designed posters using the same style for other cult movies. You can see her work here...Movie Prop Posters / Design / ShortList Magazine I have 2 questions. Firstly, am I being paranoid or has she purposefully copied my style of work, secondly, if so, is there anything I can do about it? I've tried contacting her on twitter but had no response.
