Pittsburgh’s 19th annual Art All Night was held this weekend, at the Arsenal Terminal in Lawrenceville; the all-night affair, which ran from 4 p.m. Sat., April 23, through 2 p.m. Sun., April 24, is a no-jury art show.

The event was filled with displays of local artwork and live performances, including collaborative paintings, musicians, breakdancing and standup comedians. For those so inspired, there was postcard-making and drawing with chalk. A steady crowd swarmed the beer stand, though the atmosphere remained low-key and friendly. A few attendees even brought their furry friends along. The activity continued through the night, as CP''s Aaron Warnick documents here.
