It has been the topic of discussion for days among locals and others travelling through an Aberdeenshire town.
But now the explanation behind a mysterious huge question mark which has been erected in Westhill has been revealed.
The structure has been situated at the main entrance to the town at the Tesco roundabout, opposite Denman Park.
The community council is behind the scheme, as it launches a search for an artist to create a public piece of art to mark the 50th anniversary of the creation of the town.
Prior to the 1960s, the town had been mainly farmland but with the discovery of oil in the North Sea and the subsequent boom, thousands of people flooded into the north-east for work.
Local solicitor Ronald Fraser Dean struck on the idea of creating a town, with its close proximity to Aberdeen, and the first “new” houses were built in 1968.
Now, the community council – with the backing of Aberdeenshire Council – hope to mark the anniversary with a permanent tribute to its evolution from rural hamlet to bustling oil and gas suburb.
The budget for the project is about £37,000 with the potential for further funding.
The deadline for applications is September 11, with interviews taking place on September 18. For more information visit the community council’s website at www.westhillelrick.org
