James bond domingo letter

[PrincessWellington]

I have found a book with this letter from the 60s and have no idea of the value, does anyone have any experience or a link yo a site that would value it?
Thanks

Here's some info about it

Here's an eBay listing asking £750 (but didn't sell...)

Another ebay one but only £30 this time (and still didn't sell)

I don't know what that tells you. Try going on to www.abebooks.co.uk and see what the secondhand booksellers are selling it for?

Hi Suzi - yes the eBay thing is what got my attention!

Going to ring around some dealers today
