Hello!  (This isn't about an American President, but a Russian one, but I hope I can still ask for your advice, please? :)

I have a dated, signed, and dedicated (in Russian) copy of the book 'The Art of Living' (the book is in English) by Mikhail Gorbachev, opposite the article which he wrote for it. (I compiled and edited the book and met him in Madrid, Spain in 2008.) 

I'm interested in selling the book.- Could anyone advise me on how best to go about this, please, as I'm a complete novice?

Many thanks!

Claire
