I've lived in the neighbourhood for the past 25 years and had always suspected that this small grocery store was a former movie theatre. A little research on the City's archive turned up this photo.
The movie or Photo Play showing is Cecile B. DeMille's "Don't Change Your Husband".Released in 1919 and starring Gloria Swanson.
