Alexa here. I recently came upon the work of Peter Strain and was instantly wowed. Peter is an illustrator living in Belfast who has a vibrant, ink-saturated, dirty design aesthetic. He also happens to be the artist-in-residence at the Queens Film Theatre in Belfast, so he has focused much of his time on film posters for the indie cinema house. And, lucky for us, he is selling prints of many of these posters at his shop. Here is a sampling, but really, you should check out all his work here.
More including Memento and The Lost Boys...
