The 1992 Ford has become a fixture at many downtown festivals and Garden Station events over the years.
You can't miss it -- and Hurwitz, a hippy do-gooder if there ever was one, designed it that way.
The Hillcrest neighborhood resident has been giving away books for more than 20 years.
"Why? Various reasons -- keep the books from getting trashed, encourage literacy, provides a soapbox for my political views, and I'm a socialist," he told me.
The retired Wright State study skills instructor started gluing toys, bottle caps, googly eyes, wine bottle corks and an assortment of other stuff to the truck eight or nine years ago to attract people, and as an art project.
Hurwitz normally doesn't take donations, but last year, about $1,500 was raised through a GoFundMe campaign to help make mechanical repairs.
Hurwitz estimates that he's given aways as many as 10,000 books a year from the moving canvas.
You've seen it, but have you really?
