The Postal Service issued a high-denomination Floral Geometry stamp Feb. 24 at the San Diego Stamp Show.
The $10 stamp joins last year’s $2 and $5 Floral Geometry issues. Each denomination is a different color: The $10 stamp is red, the $2 stamp is green and the $5 stamp is purple. They were designed to be used with packages and large envelopes.
The designs began as an exploration of the patterns found in nature.
The images feature a series of overlapping geometric shapes — circles, ovals and triangles — that reflect the symmetry of floral patterns. As the denominations rise from $2 to $5 to $10, the designs become more complex.
A foil treatment adds glimmer to the stamps, which were designed by the firm Spaeth Hill. Antonio Alcalá was art director.
The Floral Geometry stamps can be purchased at Post Offices and usps.com.
