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 isPortrait of a Man, at 3,595 × 4,000 pixels: enough for a 12 × 13.3 in print at 300 dpi, or 24 × 26.7 in at poster sharpness.
The Met flags one of these as a collection highlight: Venus and Adonis.
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.
