This eccentric 17th Century painting, entitled Concert of The Birds, is due to be sold next Tuesday by auctioneers Christies at their Paris saleroom. The work, by Paul de Vos, is expected to fetch upwards of 250,000 Euros (£231,000). Not often that you see a whooper swan and great spotted woodpecker in the same image. Somehow, it is hard to believe the music would be all that sweet on the ear.
