World War II poster encouraging the public to address letters correctly and clearly. The image is of a stamped and franked envelope, upon which are the words 'Address', with a rectangular red outline around it, and 'your letters correctly'. To the left of the envelope is a red arrow with the number '1' on it. The envelope casts a shadow, upon which are the words, '- and clearly and completely', and to the left is a red arrow with the number '2' on it. The background is in shades of blue and grey, and suggests an empty landscape, and to the right of the image is a red GPO post box, smaller in scale, as if in the distance, and also casting a black shadow. The stamp is worth 2 and a half old pence, and the monarch depicted is george VI (in profile and silhouette). The artist has signed himself 'Eckersley .44' along the edge of the envelope's shadow.

Note: At some point the poster has been folded vertically along the centre, and the left side of the poster is imprinted with a 'ghost' of the image from the right-hand side.
