Arweave permaweb linklink2 or data hosted directly on ethereum blockchain. You could also use fountain coding to chain multiple qr codes and encode all the data directly in them. It would probably require some crank operated flip book like contraption behind transparent glass.
As for the service, it doesn’t look very expensive to run, 1 or 2 new clients a year is probably enough to sustain it. I would expect it to run so long as the owner is alive, ironically.
