Cut outs by Keren Dee.

Keren Dee is a former Wimbledon student :) and exhibited as part of the Bloomberg New Contemporaries last year, which I went to see. She uses postcards of other artists work from museums and galleries and creates new assemblages by cutting and collaging them together. She invites you to "consider a new perspective and way of thinking." They are playful and appealing and I think they work wonderfully, especially as a set in the series how they were displayed.
