the blue quasar:
chapterhouseinc:like if Taco Bell, KFC and Pizza Hut all had the Pepsi logo for an icon--their parent company....
That would be very strange. Each restaurant has its own logo. That seems more realistic.
The only one that I wish would be updated would be the "Tim Horton's" category that I adopted/took over. All other national chains get their specific logo, but Tim's just gets a doughnut.
Oh well. I'm not going complain, just make comment as the opportunity arises naturally.

I think chapterhouseinc was expanding on the previous post -- that using the NPS logo for NRHP is like having the Pepsi logo for those restaurants.
Here's a site that uses the plaque as an icon. It's kind of bland for such a popular category, but I do think it's more fitting.
