Photographic Card Deck of the ElementsTheodore Gray
This is the most detailed and beautiful set of reference cards ever produced on the subject of the periodic table. The front side of each 127 x 127 mm card shows a full-size photographic image of the element, while the reverse gives scientific information including atomic weight, density, melting and boiling point, valence and the percentage of the element found in the universe, the earth's crust, the oceans and in man.
