Hi! you should google something like "buy final fantasy posters" Someplace llike animecastle.com have ff posters, although Im not sure if they have that exact one. You can probably email their support and have them point you in the right direction if they dont carry it. there are also places that will MAKE a poster for you, for example, places like kinkos has a poster/banner making machine that can make you posters damn near any size you want with that jpeg you showed. You should call them and find out how the process works, how much it would cost, and any other places that can make them. (shops that specialize in making signs and banners and posters for business or personal use are everywhere) Its a good option if you cant find that particular one anywhere. Also, try looking really closely at your friends poster and see if theres a company name or logo on it somewhere, a copyright or trademark, or something that tells you who made it, and try contacting them directly. Good luck! that would be a bada$$ poster for sure!
