Nabisco Shredded Wheat Promo, c1930

One side of a die-cut fold-out published by the National Biscuit Company ("Bakers of RITZ, UNEEDA BISCUIT, and other famous varieties").

Actually, the section furthest right is what the ad looks like when it's all closed up. The piece folds and unfolds accordion-style. A nice design, despite the weird bodiless heads involved.
