What Are Typewriter Eraser Brushes?
The circular objects in the image are typewriter erasers, which came with a small brush attached to them. The erasers themselves were made from soft materials like rubber, often infused with fine abrasives. This combination was designed to remove ink or typewriter ribbon marks from paper, which was the primary method of correcting mistakes on a typed document before the advent of white-out or digital editing.
The small brush on the tool was used to gently whisk away the eraser debris left on the paper after erasing a letter or a word. In an age when typewriters ruled the business and literary worlds, these tools were essential to maintaining neat and professional-looking work.
A Snapshot in Time: When Eraser Brushes Were Essential
In the early to mid-20th century, typewriter eraser brushes were as common as correction fluid or digital backspace keys are today. Every typist had one on their desk because, despite their best efforts, mistakes in typing were inevitable. These tools allowed for correcting those mistakes without the need to retype an entire page.
Back then, carbon paper was often used for making copies, so one mistake could mean fixing multiple sheets of paper. Eraser brushes were gentle enough not to tear the delicate paper yet effective at removing the erroneous marks.
