As far back as 1997 a Swiss artist came up with and produced for exhibition a series of small signed edition pieces of artwork the size of commercial trading cards at 5 x 4 inches outer size with an aperture 3.5" x 2.5".
The concept behind these creations was simple enough.. super small almost minatures allows for arelatively low cost purchase and a way of circulating image svery very quickly amongst like minded people.
