"I think the works will fit in wonderfully in the gallery at National Museum Cardiff particularly as there are two important portraits of Dylan Thomas in the collection and I'm very happy that this will be part of the Dylan Thomas centenary celebrations."
Oliver Fairclough, keeper of art at the National Museum Wales, said it was "a privilege" to exhibit the work.
"The exhibition will be a ground-breaking, experimental show of the highest quality that combines unique visual images with the spoken word," he said.
"Blake has a fascinating history of working with museums and of inspiring audiences and I'm sure this exceptional exhibition will have a major impact on new and existing visitors to the museum."
The Dylan Thomas 100 festival is funded by the Welsh government, the Arts Council of Wales, and Swansea, Carmarthenshire and Ceredigion councils.
The year-long festival will take place in 2014 and will include theatre performances, visual arts, comedy, television, film and exhibitions held across Wales.
