This slide is labeled "halfway off" meaning the pavement has been partially removed in order to repave. Streetcar tracks are clearly visible.
There are several businesses in view. One in particular is the Geo. W. Kirwan & Co. According to a 1914 city directory, the Kirwan business (a men's clothing shop) was located at 13 N. Charles Street, Baltimore, Maryland.
The "moving sign" for the business next door (to 319 N. Charles Street) also helps determine the image is of Baltimore.
Several things to notice in this image. On the left, there appears to be a police officer/crossing guard holding a sign and helping someone (in a white outfit) with a package cross the street.
There are several automobiles in view and a street car making its way up the street.
