They're lovingly known as Nina and Gramps. Now the world gets to share their 61-year love story after the couple's photo shoot went viral. The theme was inspired by the Pixar movie Up -- and features bunches of big, colorful ballons with whimsical touches of vintage travel.

As the tech site Mashable explains, the photo shoot was all the more special because the couple only has one photo from their wedding day after their photographer stood them up.

The pictures were taken by Cambria Grace Photography on Boston's Old Northern Avenue Bridge.
