Here are a range of toys that are all - effectively - nothing! Consisting of air, zero volume containers, blank pages in a book... the list goes on. Yet all of these toys have been sold commercially. In fact, we even sell one of them in the Grand Illusions Toy Shop!
Are they the ultimate expression of less is more? Or do they simply demonstrate that the product does not matter if the marketing is good enough?
I suppose we would probably say that they certainly all tend to be clever examples of packaging, with an ironic line in descriptive text!
