We came across an awesome old photo on Flickr of the York Theatre, sitting at 3640 Georgia Ave. NW, in Petworth, near the intersection with New Hampshire Ave.

The theater opened on November 27th, 1919 and was the eighth theater in Harry Crandall’s chain across the city.
The building is still there, albeit in a much uglier state. Check it out below in Google Street View, and check out this good piece written in the Washington City Paper a while back by Lydia DePillis.
