Below is a war code 10 Shilling note with a small portion of the face printing on the reverse (top left edge), caused by the previous note being folded whilst being printed. This left some ink residue on the bed of the printing press which was then picked up by the next note (this one pictured) resulting in some of the face printing on the reverse of the note, illustrated in the zoom image.
