Promoting the game of Gobstones
The association has tried earnestly to bring the game to greater popularity, but with little success. Its recruitment campaign, "Give Gobstones A Second Glance", features a poster with an accompanying picture of Hopwood being squirted with an eyeful of gunk, which may have done more to drive interested parties away than promote the game.
