I recently received not one but two Henry VIII & His Disappearing Wives mugs as gifts from different people. I guess my interest in the Tudors is no secret.
This is a 12-ounce coffee cup decorated with familiar images of Henry VIII and his six unfortunate queens. (Well, they're all familiar to me except the picture of Katherine Parr, which I don't remember seeing before.) The box says, "Pour in a hot beverage and watch as Henry's six wives vanish!" And that's exactly what happens. After you put a hot drink in the mug, the pictures of Henry's wives turn white, leaving you alone with King Henry as you enjoy your beverage. It's a ghoulishly amusing gift.
The cup is microwave safe but can't be put through the dishwasher. The box suggests gently washing it with warm water and soap. I did that twice with success. When I tried it a third time, the decal with the picture of Henry VIII started to peel off. So now Henry is disappearing along with his wives, which seems only fair.
If you buy this, know that the gag element might not last for long. And try to wash the inside without getting the outside wet.
By the way, I see that there's a similar Van Gogh Disappearing Ear Mug on Amazon. Terrible, isn't it.
