Felix Gonzalez-Torres was an artist who made sculptural works out of things such as piles of sweets and stacks of posters. These then change over time as the audience is invited to take one.

I love that subtle interaction and also the beautiful simplicity of the stack of posters. I have seen Torres’ work before and had a copy of the poster with the clouds. They are much more about taking something with you than necessarily the best quality of the print for example.
