Although newspaper posters are now suppressed, one fairly frequently sees the paper-sellers displaying a poster. It appears that old ones are resuscitated and used, and ones with captions like “R.A.F. raids on Germany” or “Enormous German losses” can be used at almost any times.
 ‘Suppressed’ implies censorship; such posters were forbidden simply to conserve raw materials and economise on imports, thereby saving shipping space. Peter Davison
