A standard 4:3 display (1280x960) title screen for Conquests (although it could be used with any version of Civ3) based on the painting Knights Dueling by Eugène Delacroix. Replace x_title.pcx in your Civilization III\Conquests\Art folder with this to use this background. Created with Adobe Fireworks; modified to screen size and Civ3 format with GIMP.
Thread about widescreen title screens (including a few others) is here.
