h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Well that's me.
I've joined this vast enterprise in the hope that someone else, immediate family members excluded, has an interest in the subject which has been occupying my spare time for months.
It all began with an inheritance last year. I came across an abstract painting which I had last seen as a small child (close on 50 years ago). It spooked me at first but, on doing a bit of research, I began to understand it and was hooked on the project of finding out as much as possible.
Sadly, I became disillusioned by the BBCi website on antiques. I posted two messages there asking the experts if they knew an approximate value of the painting. Not a dicky bird in reply!
Don't want to go into too much detail now - have enough to write a thesis - but a brief description follows:
The painting is by the Victorian spiritualist and medium Miss Georgiana Houghton also styled as The Sacred Symbolist. It's an example of automatic painting executed by Archangels through the medium. It's a gouache and a little smaller than A4 size.
In 1871 Miss Houghton's work was exhibited in London. There were 155 paintings, all catalogued and annotated. Mine is there in the catalogue. Some of the paintings later went to Australia for an exhibition there but I don't think mine was one of them. There are 35 of these paintings still in Melbourne in the church of the Victorian Spiritualists Union.
The maths is easy - I figure that if I were to try and account for the other paintings at that exhibition then I would have to track down 119 of them. Where are they now? Well I guess some of them have been destroyed by now but surely not all of them.
I'd be glad to share what I know if someone else has information about any of the other paintings.
