"Evoking feelings of warmth and playfulness, each stamp shows a cute and cuddly animal resting its front paws on a big red heart. Sure to add a bit of whimsy to your valentines, these adorable stamps are also suitable for use on letters and cards throughout the year," a press release from the USPS states.

Animal lovers can pick between either a puppy or a kitten leaning against a big red heart to send mail to their loved ones.

USPS celebrate 50 years since the first Love stamp was issued with two new Love stamps, one featuring a kitten and the other a puppy with their front paws resting atop a big heart. The word “LOVE” is featured in all caps behind each animal. The stamp designs were painted with oils on wood panel, then scanned and edited digitally. Art director Ethel Kessler designed the stamps with original art by Chris Buzelli.
