From the back cover:
ALL THE IMPORTANT RULES, CHARTS, AND MAPS AT A GLANCE!
The Keeper Screen is an essential play aid for those running games of Call of Cthulhu.
This is a 3-panel Keeper Screen mounted on thick hardcover stock, folding out to 34 inches wide. One side, intended to face the players, portrays glorious artwork. The rear of the screen, the Keeper’s side, collects and summarizes important rules, statistics and charts, to assist the Keeper when running games.
Inside are two ready-to-play scenarios set in Lovecraft Country during the 1920s: “Blackwater Creek” and “Missed Dues.” Twelve ready-to-play pregenerated investigators, and color maps of Lovecraft Country, the World of Cthulhu, and Arkham Environs.
User summary:
Bundled pack includes three-panel landscape screen and 100-page letter-size Missed Dues & Blackwater Creek double adventure book.
The adventure book differs from the Missed Dues and Other Adventures book which was made available to Call of Cthulhu 7th Edition Kickstarter backers at Gen Con 2013: it omits the "Moonchild" scenario from that book, which is included in Nameless Horrors instead.
The "PDF + E" electronic edition includes the PDF versions of the screen and adventure book along with EPUB, MOBI, and PRC eBook formats for the adventure book.
