Thanks Innuendo. That's what I thought but I didn't want to stick my neck out.
Here's a link to the auction. There is another Queen item in there too (extract from signed contract) which could looks better to me, if it isn't a copy of course.
I've seen it, it's also no good (but not secreterial). I'd never heard of that auction house before the other day and I'm not impressed with their offerings so far, unfortunately.
