This was commissioned by The Lincoln Art Programme in 2010, to be exhibited on already-existing flagpoles on top of the Usher Gallery. 'Union' highlighted an alternate history of the Union flag. Seen the world over as an emblem of unity between nations, its actual history is fraught with change. Four different versions of the flag were produced to illustrate this alternate history, each of which have either been adopted or proposed at some point in the flag's existence.

The first version of the flag, in 1603, had the St George's Cross over the top of the St Andrews Cross. This did not sit well with the Scots and there is evidence that an unofficial, reversed, version was flown there.

In the mid 1600s came the Protectorate Jack, which also incorporated the Irish Harp in to the flag. This survived only a couple of years.

In 2003, came the 'reFLAG' campaign - the idea that the colour black should be incorporated in to the flag to represent the diversity of nationalities now living in Britain.

Then in 2007, Welsh MP, Ian Lucas, raised the issue of the lack of visual representation for Wales in the flag and proposed two new designs.
