Quite possibly the most sought after of all Disneyana of the 1950s is the Mad Hatter tea pot by Regal. It was for years misidentified by TOMART as a Shaw tea pot, but it is in fact a part of the Regal tea set.
The design is quite clever, with his hat as the lid, and the tea pot he holds in his right hand as the spout. The handle consists of a stack of tea cups held against his head by his left hand.
I first encountered this tea pot nearly 20 years ago, paid at the time what I thought was an outrageous price for it, but which later turned out to be quite a bargain. If you ever come across one, grab it!
