The Postal Service will release two stamps, Florida Everglades and Great Smoky Mountains, on Jan. 22.
The denominations are $9.65 for Florida Everglades and $28.75 for Great Smoky Mountains. The stamps were designed for use on Priority Mail and Priority Mail Express flat-rate envelopes.
Artist Dan Cosgrove created the digital illustrations for both stamps, working with wildlife photos for the Florida Everglades image and his own pencil drawing of Newfound Gap between Gatlinburg, TN, and Cherokee, NC, for the Great Smoky Mountains stamp.
The style is reminiscent of travel posters of the early to mid-20th century. Greg Breeding, a USPS art director, served as designer.
Both the Florida Everglades and Great Smoky Mountains contain national parks within them.
Both parks have been designated World Heritage Sites by the United Nations Educational, Scientific and Cultural Organization, or UNESCO, which has also named the Everglades a wetland of international importance.
The stamps will be sold in panes of four and will be available at Post Offices and at usps.com.
