Conservation. Used typewriter campaign. The War Production Board (WPB) has launched a campaign to secure 600,000 used typewriters from business firms and private individuals. These machines are needed by the Army, Navy, Maritime Commission, Board of Economic Warfare, Lend-Lease and other government departments and agencies. Don MacDonald, Washington, D.C. typewriter dealer, affixes a decalcomania on a machine turned in to the government by John Stockham, Washington, D.C. insurance man. This was one of the first typewriters thus enlisted in the war effort. The decalcomania reads: "Property of U.S. Government - severe penalties for unlawful use"
