Barack Obama first kissed the woman who would become his wife outside a Chicago ice cream shop - and now there is a plaque to prove it.
The managers of a shopping centre in the city's Hyde Park neighbourhood installed the 3,000-pound (1,361-kilogram) granite marker this week with a plaque reading: "On this site President Barack Obama first kissed Michelle Obama."
The plaque includes a picture of the first couple and a quote taken from an interview the US president gave to O, The Oprah Magazine describing their first date.
"On our first date, I treated her to the finest ice cream Baskin-Robbins had to offer, our dinner table doubling as the curb. I kissed her, and it tasted like chocolate," the plaque reads.
The sweet smooch happened in 1989 when the president treated the first lady to ice cream at a Baskin-Robbins, which is now a Subway restaurant. The boulder sits in a flower bed next to the shopping centre.
"It's a marker for the community, for posterity and tourism, too," said Jonelle Kearney, a spokeswoman for Mid-America Asset Management, which manages the shopping centre.
The Obamas will celebrate their 20th wedding anniversary in October. They have a home in the city's Kenwood neighbourhood, not far from the shopping centre.
