Maypoles were tubes of paper, about a foot long, striped like a barber's pole and full of sherbert.
The trick was to unwind them and eat as you went along. They were a favourite to buy on our way home from school. By the time we reached home we had fluorescent coloured tongues and felt rather sick.
They're one of many sweets that I would never let my own kids have today! I just couldn't come to terms with giving them a foot-long stick of pure sugar and e-numbers (but we did love them!!)
