Thumbs up for the #FourthPlinth pic.twitter.com/vMuVP0XnuN— David Trumper (@DaveTrumper) September 29, 2016 Really Good, which was cast in dark bronze to match the other statues, is the latest sculpture to feature in Trafalgar Square’s Fourth Plinth Programme, which invites world-class artists to create new works for the capital.Renowned tragicomic British artist David Shrigley, known for his wonky satirical works, told a crowd gathered for the Really Good’s official unveiling that the sculpture was “about making the world a better place… which obviously is a ridiculous proposition, but I think it’s a good proposition”. #London tells the world it is #OpenForBusiness… by unveiling a phallic giant bronze hand in the rain https://t.co/vY5eVPWp7P #fourthplinth— Toni Vorobyova (@_ToniV_) September 29, 2016 A woman told me she thinks #FourthPlinth looks ‘very suggestive’.

Witnessed unveiling of #fourthplinth from the office…a big thumb or something more phallic? https://t.co/GBdtPitiaZ— Zofia Bajorek (@DrZofia) September 29, 2016 Watch #davidshrigley’s new #fourthplinth sculpture being unveiled – it’s #reallygood! pic.twitter.com/ZDkkgr3roN— British Council (@Brit_VisualArts) September 29, 2016 It was #ReallyGood to launch the new #fourthplinth in Trafalgar Square today with the brilliant @DavidShrigley. #LondonIsOpen pic.twitter.com/iGez1zaPhG— Sadiq Khan (@SadiqKhan) September 29, 2016 As David Shrigley’s seven-metre sculpture Really Good was unveiled on Thursday, critics drew their own conclusions on the work – apparently split into two distinct camps.While many have applauded the ‘thumbs up’ sculpture as depicting a charming and positive message, others branded it ugly and phallic.

Don’t see the point in thumbing for a lift in a pedestrianised zone 😄 #fourthplinth— Tom Hunter (@ThomTrixter) September 29, 2016 Others were more positive about the artwork, saying they gave it the “thumbs up”. It may only have just made its debut, but the new artwork on Trafalgar Square’s Fourth Plinth has already managed to divide opinion. What a waste of money that could of been spent on something else #fourthplinth— Scott Clarke (@FATBOYCLARKIE) September 29, 2016 Sadiq Khan, the Mayor of London, said the thumbs up sculpture conveyed an upbeat message that the capital “is open”.He said: “What it represents is so important – optimism, positivity, the best of us. This sculpture is so important showing Londoners, tourists, that London is open.
