Input: Consider Input: Question: How many years after Wish You Were Here was released was The Wall released? Passage:Storm Thorgerson, who had done the majority of album covers for Pink Floyd, did the Echoes art which features recursive windows in an infinite regression as a nod to his own cover for 1969's Ummagumma, and the objects on each landscape refer to the Pink Floyd discography. For instance, there's the man on fire from Wish You Were Here, another wearing the Delicate Sound of Thunder lightbulb suit, dolls of the Atom Heart Mother cow and the Animals pig, a bike and both a brick wall and the hammers from The Wall. Eventually Thorgerson opted to make two images, with another used for the back cover. To create the idea on a photograph, various walls - which had varied measurements and angles to ensure that "nothing seemed to fit other than by eye through the lens." - were built and put in a country landscape in Sussex. Actors, props and fittings were set in and between those walls. The original design was one of two sketches submitted for Dream Theater's 1997 album Falling into Infinity, with the original being framed and hanging in the home of former Dream Theater drummer Mike Portnoy and is pointed out by Portnoy in his Hudson Music instructional drum DVD In Constant Motion.

Passage:Promoted lieutenant-colonel in 1852, and colonel (and commanding officer of the 5th Uhlans) in 1853, Manteuffel was sent on important diplomatic missions to Vienna and St Petersburg. In 1857 he was promoted to major-general and chief of the Prussian Military Cabinet (the King's military advisers). He gave strong support to the Prince Regent's plans for the reorganization of the army. In 1861 he was violently attacked in a pamphlet by Karl Twesten (1820–1870), a Liberal leader, whom he had wounded in a duel, for which Manteuffel insisted on being briefly imprisoned. He was promoted to lieutenant-general for the coronation of William I on 18 October 1861 and saw active service in that rank in the Danish War of 1864, then at its conclusion was appointed civil and military governor of Schleswig. In the Austrian War of 1866 he first occupied Holstein and afterwards commanded a division under Vogel von Falkenstein in the Hanoverian campaign, then in July succeeded Vogel in command of the Army of the Main.
