Love is here to stay, says the U.S. Postal Service.

The USPS has released two colorful “Love” stamps, in 37-cent and 60-cent denominations. The stamps are a continuation of the many “Love” stamps released by the Postal Service over a period of many years.

The first “Love’ stamp was issued in 1973 with a denomination of 8 cents and featured an iconic design by pop artist Robert Indiana. Since then, the stamps have depicted a wide range of subjects including flowers, animals, cherubs and love letters as well as abstract designs.

The 2002 pair of stamps display block letters spelling LOVE in a circular design. The denominations appear within the letters.

In 1984, a 20-cent stamp featured the word “Love” five times, with the “V” in the shape of a heart. The 1985 version, of 22-cent denomination, showed the word “Love” in crayon design. In 1992, the 29-cent stamp illustrated an envelope with a big red heart sealing it.

In 1989, a 25-center portrayed a pair of lovebirds hovering over a red heart. In 1991, two stamps had the love theme. A 29-cent stamp featured the world in the shape of a heart and a 52-cent stamp depicted a pair of lovebirds in a nest, with the word “Love” below.
