This is my favorite cup. I found it at the Good Will in the city. My first thought was "1960s". The very next (?) day, my Bobby and I watched an old episode of Bewitched together. Lo and behold, there was Samantha in her 60s kitchen drinking coffee from a white cup that was lined with this same Aqua color! I was so tickled! This cup is now known as my Samantha cup! I wrapped it up and packed it away yesterday. Travel safely, dear!
