Here's a miniature metal tray with Grumpy, Doc, and Snow White. Imprint in lower left corner reads, "Happynak Series - Made in Gt. Britain." In lower right, "By Permission Walt Disney - Mickey Mouse Ltd."
A similar tray pictures Mickey Mouse carrying a stack of dishes. Probably from a different tea set but with the same copyright markings. Measures 6.25" x 4.125".
A tea pot with early Disney characters. Same markings on bottom. Dimensions: 1.75" tall x 4" wide (spout to handle).
A cup probably from the same Mickey/Donald series. Size: 2" diameter x 1" tall.
A Mickey saucer, 2.75" square.
In the Snow White set, cups were issued with a Dopey litho on the bottom. Size: approximately 2" diameter x 1" tall. The Dopey saucers measure 2.625" diameter. (A couple of Mikey/Donald cups are also shown in the photos below.)
Cups have removable handles.
