Annmad you are a star!

Your link says:

Voltaire : The History of Candide or All for the Best. London, C. Cooke, ca 1799. Cooke's Edition/embellished with superb engravings. 12mo, Full calf with gilt decoration and title piece to spine. Binding held with tape. pp171, 2 full page engravings dated 1798 and 1799. Front free endpaper watermarked 1797. Engravings and near pages foxed, all other pages are tight, bright and clean.

My copy has no (e) in "Candide" but the rest seems to fit but I can't see any watermarks on the endpaper and mine has no title on the spine unless it has rubbed off with age.

Thanks so much though! They price it at £55.00 ..ish, so I will keep your link and see what happens :}

Thank you again - I should have Googled the publisher so thanks for all the extra info from both posters.
