Illustrated above are two of the 20 hand-coloured litho plates, many showing the Crystal Palace in the background and each with a rhyming couplet below, that make up Blondin’s Marvellous Feats. This rare concertina-style panorama of c.1865 made £1400 in a Dominic Winter (19.5% buyer’s premium) sale of December 15. Condition was not of the best, but the saleroom could not trace another copy at auction.
