‘Marlene Dietrich: Dressed for the Image’ and ‘Antebellum Portraits by Mathew Brady’ at the National Portrait Gallery: Two exhibitions open this weekend at the Smithsonian’s shrine to portraiture. “Antebellum Portraits” explores the work Mathew Brady did before his Civil War photography, having already achieved acclaim as a portrait artist in the rapidly evolving field. “Dressed for the Image” dives into the life of Marlene Dietrich, one of the biggest Hollywood stars of her time, with photographs and film clips among the 45 objects on display. “Dressed for the Image,” through April 15, 2018. “Antebellum Portraits,” through June 3, 2018. Free.

The debut of AwesomeCon's official beer at City Tap HouseFrom the Nationals to the Craft Brewers Conference, everyone has an official beer these days, and you can add AwesomeCon to the list. Ellicott City's Manor Hill Brewing was tapped with drawing up a new ale for the annual gathering of fans of comics, sci-fi and cosplay, and came back with Atomic Smash, a farmhouse ale flavored with pink guava fruit. The label features an original work by comic artists Cuddles & Rage, who will be appearing at AwesomeCon. 5 to 11 p.m. Free admission; beers priced individually.

Nikki Glaser at DC Improv: Last year, comedian Nikki Glaser hosted the provocative, sex-positive show “Not Safe With Nikki Glaser” on Comedy Central. The network passed on a second season, but Glaser is still down to yuk. She’s hitting the road and working on new material that will likely touch on sex — just not the whole time. Through Sunday. 7:30 and 9:45 p.m. $25.

There will be food trucks on hand (though you can also bring your own snacks), and bands will provide the entertainment. 1 to 7 p.m. General admission: $25 in advance and $33 at the door, includes five drink tickets; VIP admission: $40, allows entry at noon and 10 drink tickets.
