The International Poster Gallery celebrates its 20th anniversary this month with Tour de Force, an exhibition and sale of 40 rare and significant posters from the archives.

Though he’s perhaps best known for his work in the U.K., Simon Amstell's U.S. fan base is growing quickly, and with good reason. The comedian offers a dark and self-deprecating mix of personal anecdotes, failings, and philosophical discussion that are at once relatable and shamelessly funny. We chatted with him at home in London as he was preparing to hop across the pond; see him at the Wilbur Theatre on April 19.

 On Marathon Monday in 2013, Richard “Dic” Donohue was just another man in uniform, working as a transit police officer for the city of Boston. One year later, he’s become a symbol of survival after being struck during a shoot-out in Watertown between police and Tamerlan and Dzhokhar Tsarnaev.

 The first time John Stoller ran the Boston Marathon, it was sort of an accident. A casual runner, he had planned to jog alongside a friend for a few miles and then stop in Wellesley, but he kept challenging himself to run farther until he finally decided to just finish the race.

 Brothers JP and Paul Norden were cheering on a friend at last year’s Boston Marathon when the bombs went off. Standing directly beside the blast, the brothers—and Paul’s girlfriend Jacqui—were severely injured. Both JP and Paul ended up losing part of their right legs.

Running her first Boston Marathon in 2013, Shonna Cirone made it up Heartbreak Hill, ran through the Wellesley “scream tunnel,” and was almost to Kenmore Square when she was instructed to stop. Something had happened at the finish line, and the race was over. Unable to reach her friends by phone, she decided to continue walking into the city. 

Dear Boston is an exhibit featuring select pieces from the Boston Marathon memorial at the Boston Public Library.

 Looking for a way to express his emotions after the Boston Marathon bombings, photographer Chris Padgett decided to get inked—and he wasn’t the only one with that idea. When he realized how many other people were getting Boston-themed tattoos to commemorate the tragedy, he started documenting their body art.
