Question: How many years after Thorgerson designed the cover with the man on fire for Pink Floyd did he pass away? 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.

Question: Of the venues in which Longaretti exhibited his works in 1942, which was the newest? Passage:Upon completion of his degree studies at Brera in early 1939, he was drafted by the Italian military for service in World War II. He was deployed to Slovenia, and later to Sicily and Albania, and when his tours of duty were complete, he would participate in art exhibitions. He continued to paint during his service, even when on the front lines, committing to canvas images of "dramatic testimonials" considered prohibited, such as Albanian villages razed by Italian troops. At the end of the war, he also began working on frescoes, glass art, and mosaic art. In 1942, he exhibited works at the Venice Biennale and at the Mostra degli artisti in armi ("Artists in arms") exhibit at the Palazzo delle Esposizioni in Rome, where he presented three watercolours and seven pen drawings, all having a war theme. By this time, he was a sergeant for the Genio Ferrovieri. His first personal exhibition occurred in 1943 and was presented by Raffaello Giolli at the Galleria La Rotonda in Bergamo. He dedicated himself to teaching and the creation of works of sacred art in 1945. He would exhibit at the Venice Biennale again in 1948, 1950, 1956, and 2011, and was invited to exhibit at the Rome Quadriennale in 1952.
