Drafting Pens and Pencils
Pencils
Pencils also have changed over time. This page shows one example of slate pencils as well as boxes of the more familiar wood-encased pencils. The collections have both an early instance of a mechanical pencil and a 20th-century example, the latter with a famous connection. Draftsmen needed pencil leads to insert into other drawing instruments, and one engineer even donated his metal pencil box.
