This title was released at the end of last year. The author publishes his games himself. All components in the game are therefore made by Gary. His games can be purchased on eBay, where a few more copies are available every few weeks. Unfortunately, little is known about 1878. A short description is available on BGG, which we have included below, as well as photos of all components.
