Hi, I'm Emily the designer of Fran Sans. One of the Breda cars is going to the California State Railroad Museum, and it has the displays in it. I also suggested to the Letterform Archive in SF that they may have interest in it. I do know they've archived some of the NY subway curtain displays, so I think it's only fair they save one of these in their collections too.
That's one, but what about all the rest? If someone at the service garage has any sense, they'll make sure the displays end up on eBay, not a crusher. I can see a bunch of nerds turning them into all sorts of wonderful things.
