The document summarizes four artworks - The Astronomer by Johannes Vermeer from 1668, Bedroom in Arles by Vincent van Gogh from 1889, The David by Michelangelo from 1501-1504, and provides a plan to merge the photos by placing The David modeling in Bedroom in Arles with The Astronomer taking a photo. The goal is to create a funny collage despite the subjects not knowing about cameras at the time.
