The original decals are like the identity card of the typewriter. The more signs and documents it has, the better we can identify where and when it was made.
The passage of time, the environmental conditions, as well as the way of storage or use leave a great mark on the typewriters. That's why most typewriters have their paint destroyed.
70% of the typewriter's appearance is made up of keys. Unfortunately, the keys turn black over time and are covered in mold and rust. Because of this, the surface can often suffer irreparable damage.
