The equestrian statue of the Duke of Wellington outside the Gallery of Modern Art has been given a Yes flag by some cheeky independence campaigners.
For good measure, the Duke himself is wearing a Yes cone.
One passer by said: "You wonder how they managed to get the flag up there without being seen."
The statue and its traffic cones have become a famous Glasgow emblem.
Last year, however, Glasgow City Council announced plans to deter the vandalism of the statue by raising the statue to make it inaccessible.
But a protest petition attracted 10,000 signatures, and the council later backed down.
The Yes materials were taken down yesterday.
A council spokeswoman said: "They have been removed, as the Referendum Act 2013 is clear - council property can't be used to promote either side in the referendum."
