Cups are made by Dallas Ware, in good condition, insides very shiny. Do not appear to have been used much, if at all. No cracks. They do all have some surface spots, see photo 5 for example.
Saucers are made by Boonton Ware. They do show some surface scratches, and one has a small burn mark on the bottom (see photo 4).
