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 isJo, La Belle Irlandaise, at 4,000 × 3,394 pixels: enough for a 13.3 × 11.3 in print at 300 dpi, or 26.7 × 22.6 in at poster sharpness.
The Met flags 2 of these as a collection highlight: Woman with a Parrot and Young Ladies of the Village.
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.
