Let's fly this flag by New Year's: everybody at least 10% in war bonds.

A blue flag flies on a gold pole. The flag has a white silhouette of the Concorde Minute Man, twelve white stars circling him, and a white "T" in the lower right corner. A red, white, and blue target is to the bottom left of the flag, containing the text, "Everybody at least 10%".
