The Movie Poster Archive is a Tumblr page created by Nicolas Ortega devoted to building an repository for his posters based on a "first sight" interpretation.
Now that can mean one of three things:
1. The first sight interpretation is based on the original release poster.
2. An interpretation based on seeing the original trailer just once.
3. Based on an interpretation of seeing the actual film just once.
All three it turns out. Ortega's "archive" encompasses take-offs of the original poster art, snippets of things shown in the trailer and compressed visual theme of the whole film.
The results are wonderful and obviously have a lot of detail and first and second and third thoughts put into them.
