I was pleased to see that you used the picture by Lowry of children coming out of school for your poster in the supplement of May 14, especially as it was the same one used for a stamp by the Post Office in the Sixties. But I see that the stamp is the reverse of your poster. One has been printed back-to-front. Has someone boobed? Or should we use the usual teaching device and say that this was done deliberately to test the attentiveness of our children?
