In 1961, Prater was approached by Gordon House with the request to make a screen print for him. This was the first time that Prater had made something for an artist. A year later, at the initiative of Richard Hamilton, Prater made screen prints of work by 24 British artists, affiliated to the Institute of Contemporary Arts (ICA) in London. These were completed in 1964 and formed a portfolio that was sold to raise money for the ICA. For many artists, this was their first encounter with the screen printing technique. Some of them, including Tilson, Kitaj and Paolozzi, continued to work closely with Prater in the years following. In that period, Kelpra became a by-word for artists: a screen print had quality if it had been printed at Kelpra.
'Printed at Kelpra' is on show from in the Print Room.
