On a visit to his elderly artist-parents, Teller found a dusty portfolio of cartoons that his father drew in 1939. Teller asked about the people in the drawings: the streetcar operators, waitresses, soldiers, bums. And Mam and Pad (Irene and Joe) began to unfold the hidden history of their world before their Bundle of Joy came along. Out came the Hobo Shoebox, full of letters Joe wrote while riding the rails during the Great Depression; their daring photos as art students, eloping to escape their feuding families; and the War Trunk. Readers stand beside Teller as Pad teaches him why using a ruler in painting is evil; join Mam as she interprets the designs hidden in Joe's "art pancakes"; and enter the world of a most peculiar, philosophical, funny, and loving family.
