How Housing Works Bookstore Cafe sometimes finds rare books (it's awesome!)

From housingworksbookstore:

No really, this is how we find rare books sometimes.

Volunteer: Does it matter if one of these dollar books is signed?

Staffer: Probably not. The truth is, most author’s autographs aren’t worth anything.

Volunteer: Oh, okay. Does it matter that it’s signed by Robert Frost?

Awesome!!

I have a 2 dollar bill signed by Isaac Asimov. Guess that’s not worth anything, huh. :(
