Greatest of Family Games
The most entertaining and instructive game of the century. It delightfully teaches American geography, while it is to young and old as fascinating as whist. Can be played by any number of players. Sent by mail, postage prepaid, for fifteen 2 cent stamps. The Trade Company, Boston, Mass.
I presume the name refers to the map’s changing face as the United States acquired land over the years, but I can’t be sure. Though this advertisement appeared in many papers of the time, I haven’t found anything else about the game.
I’ll keep looking. It seems to me this game would be a fascinating snapshot of the United States at the end of the nineteenth century.
