First of all an apology to Michael Pritchard and others, this discussion should really have been here rather than the Blog, so I am continuing it here.
The attached cropped images are from my collector friend's collection. They are from stereographs of people involved with stereo in some way.
I will add another image where both Ron and I are unsure. It's called "The Inquisitive Maid". It is certainly an optical object, but is it a form of Brewster viewer?
No photographer nor publisher of views on the cards themselves .

Yes Graham, having reexamined the scan I think you are correct. Thanks

Hello Stephen
Pretty sure this is not a viewer - the maid is trying to read a letter , without opening it , presumably sent to her mistress , there are a number of similar views .
