We just listed a lot of vintage Federal and Fire King coffee mugs. We love vintage coffee mugs but our cabinet runneth over so we picked out some we were willing to part with. The all white milk glass mugs are one of my favorites. I love the idea of baking cakes in the coffee mugs for a children's tea party.....not that I have ever gotten around to trying this but I hope to at some point. You can get some inspiration here.
