First up the 2012 winning entry is by Elmgreen and Dragset, titled 'Powerless Structures, Fig. 101' it depicts a child riding a rocking horse. There is an interview from the artists here.
The 2013 commission goes to Katharina Fritsch's blue cockerel titled 'Hahn/Cock'. Interview from the artists can be found here.
It's a shame the 'Battenberg' by Brian Griffiths didn't feature as that was my favourite out of the six shortlisted. However i'm still excited to see the winners as i'm sure they'll make a great edition to Trafalgar Square.
