Dungeon Master's Screen

From the cover:

Keep the Action Moving

This Dungeons & Dragons Roleplaying Game accessory provides the Dungeon Master with a collection of tables and lists useful during game play... this screen speeds play and keeps the action on track.

The heavy cardstock, four-panel Dungeon Master's Screen also keeps players from seeing what's coming up in the adventure--use it to hide your encounters, maps, miniatures, and even dice rolls from prying eyes!
