Graf Bobby und Baron Mucki - Geschichten aus dem alten Wien, Heimeran Verlag 1941. Graf Bobby is the smaller one with the monocle.
Graf Bobby is a traditional Viennese figure of fun. The jokes are dialogues with his friend Baron Mucki (in another tradition Baron Rudi). Graf Bobby is an extremely stupid person but sometimes profound in his childlike reasoning, always amazed at a world he’ll never comprehend.
Here’s a translated example, the first joke in this collection:
Count Bobby and Baron Mucki have gone to the opera house. During intermission Bobby nudges his friend, points discreetly to a box and whispers:
"Look, there ... the countess Esterhazy!"
"Go away", says Mucki, "Countess Esterhazy is dead a long time ago."
"Is she? - But look, she's moving!"
