This card combines science with a modern pop-art esthetic to depict a protein molecule that spells the word "peace." A holiday greeting can be added inside. Inside of the card states: The front design represents a protein formed from amino acid units whose shorthand initials spell the word peace (P:proline, E:glutamic acid, A:alanine, C:cysteine, E:glutamic acid). In the peptide, carbons are rendered in the familiar stick format, while the oxygens (red), nitrogens (blue) and sulfur (green) are depicted as circles in their traditional color-code.
