Apparently, this typewriter with the Underwood logo was (and still is) the largest ever created. Although it was made almost a hundred years ago. The exact date of production could not be found, but in the "Modern Mechanix" for December 1930 it was referred to as a finished and working mechanism.
For the first time, the miracle mechanism was on display in a conference room in Atlantic City, New Jersey, where it was on display for almost ten years. The initial construction required the company to invest one hundred thousand dollars over three years. In 1939, the machine was transported piece by piece and reassembled in New York. This was done for the Dawn of a New Day exhibition for advertising purposes by Underwood.
All parts of the huge machine worked just like an office-sized typewriter. The prototype of the giant car was the Underwood Master model. It was "simply increased" (if you count "by weight", then in one thousand seven hundred and twenty-eight times!). The weight of the mechanism was fourteen tons, and the height was two and a half meters. The typewriter typed on sheets of paper measuring three by four meters.
It was possible to print on it only with feet (which the girls demonstrated at the stand). Nevertheless, even so it was difficult to influence the carriage weighing one ton, and the girls were "helped" by three electric motors moving all the main parts of the machine.
They even brought an elephant for advertising! In total, the exhibition was attended by about 44 million people and all of them, no doubt, remembered The Biggest Underwood. By the way, in print media he was invariably compared to a mammoth, calling him MAMMOTH typewriter.

Sadly, after the exhibition, the giant typewriter was "lost" and there is no information about it at all. Was it taken apart and melted down, or did it end up in the collection of some eccentric rich man? This is probably not so important. The main thing is that she was. And it remains the most-most.
