The technique of screen painting is pretty simple really - it is a Baltimore folk art. You just paint both sides of the screen with white sign paint, and then draw your design on the screen with charcoal and paint it on (also with sign paint). The advantage is that with a painted screen, you can't see into the window in the daytime, but you can see out. So people in the row houses in Baltimore could sit in the window in the summer in their underwear and see what was going on and no one could see them. I've done lighthouses of the Chesapeake on the porthole screens on the boat.

This is the one I did of Sharps Island, but it was the first one I did and I have it listing about 15 degrees too much.



Sandy Point was another early one.



By the time I did Bloody Point Bar, I had gotten better at it.



Here's another red one from Kronshtadt Russia
Fort Nikolai Range Front



And this one in the same place is the Kronstadt Range Front over the fort
