Here's what it revealed:
two pulldown menus in the upper left.
a coastline in the upper right
a battleship in the water
a panzer tank to the right of Baltimore
two almost identical standing figures, one to the east and another to the north
a natural resource (grapes?) to the southeast
another panzer in the hills to the west (hidden pretty well)
another city immediatly north, where the roads converge.

Also, there seems to be an object in the hills or mountains immediatly south of the panzer in the west. Since there's a road going from it to the bottom of the map, it might be another city. Although... it looks a bit bigger than a single square.

Within or right next to Baltimore's city radii (in the area bright enough to see) there are three gray objects. One is immediatly south, one east, and one northeast. One looks like crossbones.

There's a grayed out man I missed before. You can easily see him if you zoom to about 300%. He's facing southwest and standing in the topmost cityradius square on the left.

The city square itself is irrigated.

There be another hidden panzer to the left of the pulldown menus. It's partly cut off, but seems to be facing west.

There's another hidden road. It's a thin silver curve that goes right out of Baltimore to the northeast.
