I forgot to reply earlier to this: I looked at the reproductions
included in this set (and what a great price it went for!) and laughed
at the Oldenburg Typewriter Eraser. I have a slide of it that I used to
use in my classes, but the students, including my community college
students, don't even know what a typewriter eraser is anymore. One wise
guy piped up last year, "What's a typewriter?"
