WASHINGTON (CLARKSVILLENOW) – The Postal Service will honor the nation’s brave and loyal military working dogs with a special new booklet of 20 stamps.

USPS says each block of four stamps features one stamp of each of the following breeds — German shepherd, Labrador retriever, Belgian Malinois and Dutch shepherd — that commonly serve in America’s armed forces.

The background of each stamp features a detail of a white star and a star appears in the center of each block. The stylized digital illustrations are in red, white, blue and gold to represent the American flag and patriotism.

The art was created by DKNG Studios, with design by art director Greg Breeding.

More details on dates and locations for the first-day-of-issue ceremonies are forthcoming.
