QR on the PDF
The gallery label carries a code that opens the right screen.
Smartify
Four ways into the same object: image recognition, a numpad for the number on the label, search, and a QR code. Not everybody can hold a phone up to a painting.

No object with that number. Check the label again.
Try 104, 218, 347 or 512. The numpad exists because holding a phone up to a painting is not something everybody can do, and because some rooms do not allow it.
The QR is a real one, generated at build time with qrencode as inline SVG, so it scans, it costs no request and it scales to any print size without going fuzzy. The numpad beside it carries equal weight, because aiming a camera at a wall is not something everybody can do.
