Spanish T-shirt (White)
This beautiful 2007 stamp from Spain was designed by Spanish inorganic chemist Javier Garcia Martinez and evokes a painting by Dutch artist Piet Mondrian. It is technically accurate, with the colored blocks of elements in the rational groupings of the Periodic Table of Mendeleiev. The four blank squares are the undiscovered elements that Mendeleiev predicted would exist and for which he gave estimates of thier properties. This image created by Professor Martinez is chemistry, art and history.
