Parnassus on Wheels - Christopher Morley

I warn you, said the funny-looking little man with the red beard, I'm here to sell this caravan of culture, and by the bones of Swinburne I think your brother's the man to buy it. Christopher Morley's unforgettably weird classic tale of adventure on a traveling bookstore called Parnassus, drawn by a steed called Pegasus. Not to be missed.
