Not the Sport - but I sometimes used to find a Sun left on the train and picked it up to see what they we saying
I noticed that they often had a proper news item - properly written - on the page OPPOSITE the topless picture
I used to fold the "paper" over to read the article so the picture was on the opposite so that
a) it didn;t look I was spending time looking at the picture in an interested manner
b) I could sneak glance at the person sitting opposite to see where they were looking
After Hillsborough the papers left on the train were normally another red top - for obvious reasons
