[21] At Goldsmiths College in 1968, Grylls produced an exhibition of his first photographically based pun-sculptures, each made from cardboard and called collectively 'Ludwig Wittgenstein's Palace of Pun.

His work was noticed at his final show at the Slade in 1970 by Jasia Reichardt, art critic and assistant director of the ICA.

The work Grylls exhibited in 1973 entitled 'An Indo-Chinese Punsculpture' was a large photo-mural commenting on the signing of the so-called Paris Peace Treaty.

"[11] In 1980, Grylls created panoramic collages of the sites where President John F. Kennedy on Elm Street and Lord Mountbatten in Donegal Bay were murdered.

[28] William Feaver of The Observer referred to Grylls' work as "mixed-media surveys, combining epic scale and humdrum particulars.

[32][33] Grylls as founding Chief Executive of the merged institution[34] resigned soon afterwards, announcing that he intended to return full-time to his own work.
