The U.S. Postal Service honored the late novelist Toni Morrison on new Forever Stamp in a first-day-of-issue ceremony at Princeton University.

A letter of tribute from former President Barack Obama and former first lady Michelle Obama was read and a video tribute from Oprah Winfrey was played during the ceremony.

Morrison’s novel “Song of Solomon,” was a national bestseller and recipient of tremendous critical acclaim. Considered one of her masterpieces, “Song of Solomon” invokes generations of folklore as it follows a young man’s search for identity.

The publication of “Beloved” in 1987 brought Morrison a new level of critical success. The novel tells the story of a woman who escapes enslavement but murders her infant daughter to prevent her from the same fate she did. A harrowing rumination on trauma and the lingering, even haunting nature of the past, “Beloved” won the Pulitzer Prize and secured Morrison’s reputation as a great American writer.

Toni Morrison died in New York City on Aug. 5, 2019, at the age of 88.
