Painting on Original odyssey cards

In Original Odyssey is a puzzle that when put together creates a map. It’s 20 cards that fit in five columns and four rows. The first time you assemble the map can be a challenge. A good starting project is to construct the map and then add your marks for the north, south, east, and west corners. I also marked the center of my map. Below are some photos with examples of my current puzzle map and other cards I’ve customized.
