Barber pole in the lower right of this photo marked my great-grandfather's shop. Louis Valentine Jung cut hair at that location for more than sixty-five years. The lady hanging from the window would be my great-grandmother, the former Elizabeth Mangold. Pop Jung lived to ninety-six years old.

I can't believe the clarity of this shot! I can count each and every cobblestone and brick in the buildings. 8x10 negs are awesome!

Of the gazillion fascinating details in this photo, none strike me as odd as the sawhorse on the rooftop in the lower center of the picture. It's been tilted and tethered between the upper and lower fascia, and appears to be serving as a makeshift utility power pole crossarm. With a magnifying glass I can make out what looks like a pair of insulators mounted on the sawhorse with the two wires dangling down over the roof.

This photo really shows the atmosphere of old Baltimore during the Babe's youth.
