As mentioned on another thread, I had a bit of a rummage around for an example of an ivory fan guard to show typical jointing and came up with a bunch of other fans, none of any great merit or value but quite decorative. Mostly plastic. This one may be tortoiseshell, I'd expect an imitation shell to have sticks of uniform thickness but this one has a variation in thickness between sticks of up to 50%. Back And front. Sad relic of an Ivory brize fan Bone fan, thered ribbon on the guards is under a pierced 'frame' fixed over it. Bone stick lace and muslin fan Last three are of a cheapo plastic brize fan, unusual in having its original box, the marking 'Foreign' and the use of real glass instead of plastic for the transparent lid makes me think 1930 or so. I think that is probably enough.
