Howard Liberman, "Price control. Anti-inflation window display. Well designed because it is easily read, this poster illustrates the correct method for displaying ceiling price items on the Office of Price Administration's (OPA) cost- of -living commodity list, established for all goods essential to the daily requirements of the average family. These lists must clearly identify each item, stating size or quantity and ceiling price," 1942, LC-USE6-D-005995, Farm Security Administration - Office of War Information Collection, Library of Congress Prints and Photographs Division, Washington, D.C.
