Oh well, if nobody recognises them, it's probably a good sign. They are something "in the pipeline" and have come about as a sort of by-product of something else. At present I don't know whether I am going to develop them or not.
I thought they were quite attractive, but I wondered if there was any subliminal reference that I had missed.
I'd be interested to know if anybody has a view as to what pieces like these sell for...they are moving into a sector of the market that I have not covered for some time.
