Reader Nathan just sent in this great image of a formidable 1940s-50s era bookmobile that he found in a batch of old estate sale photos. He hazards that it's from Silver Springs, MD judging from the "Montgomery County" stenciled on the side of the truck and some details in accompanying photos.
According to Wikipedia the first Bookmobile in the United States was conceived and deployed in Washington County, Maryland so this beast of a vehicle has a long pedigree.
If Clint Eastwood was playing a tough-as-nails librarian in The Gauntlet this would have been his ride.
Anyone have any old photos from inside one of these behemoths of literacy?
