Waffles are preceded, in the early Middle Ages, around the period of the 9th–10th centuries, with the simultaneous emergence of fer à hosties / hostieijzers (communion wafer irons) and moule à oublies (wafer irons). While the communion wafer irons typically depicted imagery of Jesus and his crucifixion, the moule à oublies featured more trivial Biblical scenes or simple, emblematic designs. The format of the iron itself was almost always round and considerably larger than those used for communion.
I speak from experience: a few months ago, clear out of nowhere, I was struck by a need for homemade waffles. I had to have them—and because I live in New York City and expect immediate gratification, I proceeded directly to my local discount emporium and procured a plastic waffle iron—covered in a thin film of dust—for the sum of $16.99. Back home, I washed it and hastily set about mixing up a bowl of batter. Sadly, this story has a grim ending: even after the the requisite heating and greasing, pouring and griddling, the specimens that emerged from my iron were flabby and pale—hardly deserving of the name waffle and certainly a far cry from the feast of my dreamings.
This illustration anthropomorphizes the Twin-O-Matic and notes that post-war demand for small appliances will be a "half billion dollars" (about $100 billion in 2005 dollars), and encourages dealers to sign up to sell Manning-Bowman appliances. This is actually a very sad artifact, because the Manning-Bowman company was in deep financial distress because they could not get materials -- particularly chrome -- during World War II. This was an attempt to sign up dealers so that credit and financing could be obtained to last out the materiel shortages imposed by the War. It did not work, and soon thereafter, Manning-Bowman sank into a sea of red ink. The company's assets, including its spectacular Art Deco designs, were sold to the Bersted Corporation of Fostoria, Ohio. Berstead watered down the designs and made low-priced "drug store" versions of many Manning-Bowman appliances. (The Sandwich Grill on our Kitchen Aplliances page is a good example of this "cheapening" process.) Alas, Manning-Bowman met an inglorious end, but it was merely a foretaste of the vast wave of shoddy appliances made in faraway dictatorships that suffocate the American marketplace today.
