this is some sort of measurement converter, i think. it's double sided and has a copyright from 1945. the case is rubber and has this embellishment on it: Pickett and Eckel, Inc.(picture below). it was made in Chicago, or copyrighted there, or something. it is in three pieces that slide. well, the middle one slides (see pictures). it also has a clear slider over the whole thing. here are the pics.

Doesn't that mean that the light from the star left 20 years ago? And that the star you are seeing right now, was actually what it was 20 years ago?
If that's true, then half of the stars seen in the sky don't exist anymore!
Isn't that right?
