Tracey Emin and David Hockney gift pieces to the Queen

Tracey Emin, David Hockney and Grayson Perry have given works to the Queen to mark her Diamond Jubilee.

Hockney gifted an image of the monarch's initials created on a iPad, while Emin submitted a monoprint portrait, HRH Royal Britannia.

The Royal Academy of Arts presented the 97 works, including prints and oil paintings to the Queen last month.

The Royal Collection Trust described the works as a varied selection of "the best of contemporary British art".

Martin Clayton, senior curator of prints and drawings, said: "It seems livelier and more varied than the Academy's equivalent gifts for the Queen's Coronation and Silver Jubilee.

"The Coronation gift was quite conservative, and even in 1977 there was still a feeling that individual artists were playing safe in their choice of works.

"Now in 2012 there is no sense of dutiful deference," he added.

"The artists and architects are simply presenting an example of their very best work to the Queen, and in some cases that work is very personal - such as Tracey Emin's imaginative portrait of the Queen, or Joe Tilson's [Postcard] from Venice."

Tilson's painting of a postcard has been personally addressed to Her Majesty, the Queen.

The Queen is the patron of The Royal Academy of Arts, which was founded by George III in 1768. It has presented gifts to the monarch to mark three significant events during her reign.

The works in the latest presentation have been added to the Royal Collection, and will go on display at the Queen's Gallery, Buckingham Palace next autumn.
