Here's some info...
Paper was rationed in World War Two, but comics were still produced because they brightened the lives of children. They read them from cover to cover and swapped them among each other. Their favourites included the Beano and the Dandy which are still popular today. For the first two years of the war, these two comics came out every week. After that they were published once a fortnight to save paper. The Dandy poked fun at the Germans and the Italians who were on their side. The magazine's best-known character, Desperate Dan, was shown punching Hitler out of Britain, so that he landed in Germany. The Beano also did its best to cheer up youngsters. Lord Snooty and Pansy Potter were often seen giving the enemy a kick up the backside. Other comics that were sold during the war included Tiny Tots, Chicks Own, Wizard, Rover, Hotspur and Champion.
Some other info (probably printed after the war though)
