Two years ago, the Tate gallery commissioned Hannah to stock their shops with her London themed pop-up cards. The initial order sold out within one week (one design in one day). Ever since, popularity has increased along with the variety of different designs. Each card is a hidden secret, an inside out card, allowing the purchaser to write on the outside, giving the receiver the wonderful surprise of a pop-up on opening. This is an artwork in itself that can be kept and framed.
