Okay so one with the lady seems as if she is bolting something in with a screwdriver. So the caption "It's our right too" seems to mean that the woman also want power in America. That they are American and should be given the same rights as the American men do. Picture two seems as if there is a aviator during WWl and is describing how the war was caused by whoever started it and their rebuttal is "We'll give'em hell!" Lastly the third picture looks as if a boat is sinking and if you spread any vital information "Loose lips might sink ships" simply means that anything that you might say in that era that could affect the ongoing war spies and other enemies might listen in and report causing failure in the war.
