Each card shows the largest print the Met's file makes at 300 dpi without cropping — that's the sharpness you'd want for something you'll stand close to. The biggest file in this set isYvette Guilbert, at 4,000 × 3,494 pixels: enough for a 13.3 × 11.6 in print at 300 dpi, or 26.7 × 23.3 in at poster sharpness.
The Met flags one of these as a collection highlight: Moulin Rouge: La Goulue.
Every page has a size chart against standard frames, the museum record, and the frame and light that make a print look like it cost more than it did. The file itself is free. It always was.
