A range of calendars that feature the roundabouts of English towns has proved a popular stocking filler this Christmas.
The first calendar was produced last year as a joke
The calendars depict traffic islands from Bolton, Croydon, Grimsby and Cleethorpes, Milton Keynes, Redditch, Slough and Swindon.
They were devised by Kevin Beresford, who runs BB Print Digital, based in Redditch, Worcestershire.
Mr Beresford said that calendars, which have featured on Graham Norton's TV chat show, have been a big hit with people looking for a Christmas gift with a difference.
He said Croydon was the runaway success this year, accounting for about 70% of the 5,000 calendars already sold.
"The irony is, there aren't many roundabouts in Croydon, which is why we called the calendar Rare Roundabouts of Croydon."
Mr Beresford's first roundabout calendar was published last year and featured the traffic islands of Redditch.
One calendar depicts a roundabout from BBC comedy The Office
It was originally intended as a joke, but the publicity the idea received led to a surge in sales and prompted requests for BB Print to produce calendars reflecting the roundabout heritage of other British towns.
Mr Beresford said that orders have flooded in from all over the world, including the famous Universal Studios and Scotland Yard.
The seven towns featured on this year's editions were also selected for their unusual islands, such as Swindon's so-called magic roundabout - a cluster of five mini-roundabouts.
The Slough calendar features Brunel Roundabout, used in the opening credits of the BBC hit comedy The Office.
Mr Beresford plans to produce calendars for about 20 other areas of Britain next year.
He said: "You wouldn't believe the number of letters we've had from people
asking us to do the roundabouts in their home town.
"We thought this sort of thing would only appeal to students who are into cult things, but it is a very broad church and we get orders from people of all ages looking for that gift which is just a little bit different."
Mr Beresford even plans to make the traffic islands of the Costa del Sol famous.
He said: "I went on holiday there in the summer and had a bit of a recce - it drives my missus barmy."
