From the USPS press release November 15, 2024:

This new Love stamp celebrates the universal experience of love with a work by artist Keith Haring (1958–1990). With a deceptively simple and now-iconic style, Haring’s work is instantly recognizable. This stamp features Haring’s 1985 Untitled drawing. Antonio Alcalá, an art director for USPS, believes that this drawing makes for an ideal new stamp in this popular series. “The non-specificity of the figures allows a variety of people to see themselves in this stamp,” Alcalá says. “Partners getting married, celebrating an anniversary, siblings sending each other a heartfelt greeting, or even party planners setting a positive tone for their event.”
