sliced

"The only bread baked at the Chicago World's Fair."  Wonder Bakery was the first major company to adapt commerical bread slicers.  Imagine the "wonder" that was inspired when they exhibited at the Chicago World's Fair in 1934 just a few short years after the slicers were invented.  The exhibition baked, sliced, and packaged bread on the spot.  The Wonder book of good meals:  World's Fair Edition was given out as a keepsake/advertisement to fairgoers.  It includes recipes for every course, as well as defining "whitchery," the art of making sandwiches.
