Larger (2.5 x 3.5 inches), more thematic stock certificates for use in the game. I borrowed some images of real stock certificates from the companies and tinted them to match the colors of the cubes in the game.
The Stock certificates look very nice, Isaac, but your C&O certificate is actually from the Chesapeake, Ohio & Southwestern Railroad, a small bridge route railroad that connected the C&O and the Illinois Central. Still, they do look nice!
