AFB is an elusive company to research. It doesn’t appear to be in business anymore and no information about its operation or products seems to be available.
There are quite a few of these thimbles on various e-sites but few reliable facts. Behold the fingerful that is the AFB bone china Mickey Mouse thimble:

Mickey is looking quite dapper with his red bowtie and blue blazer. His starched collar is sitting rather high but still makes our mouse look fashionable!


This would have been an inexpensive item to buy. It is simple in design with a basic white shape accented with a gold stripe. Any number of Disney characters have been printed on such pieces.

Bone china is a type of ceramic that is composed of bone ash, feldspathic material, and kaolin. It’s the strongest of the porcelain or china ceramics, having very high mechanical and physical strength and chip resistance. A distinguishing feature is its high levels of whiteness and translucency.
For another thimble of a very unusual type, check out my post on Sherlock Holmes. You’ll be able to see the Master Sleuths brain on the top of a thimble! I bet you thought his brain would’ve been bigger. Trust me, it’ll be worth the scrolling.
