Provide three specific details of of vladek being the stereotypical old Jew.

Yes, Spiegelman really plays up the stingy old Jewish man thing with Vladek. He does this on purpose. He pushes the stereotype to not only amplify the stereotype but break it down as well; it's sort of a paradox. Looking at the pages, I'm pretty sure they are similar, I see Vladek is worried only about his money (his wife Mala left him). He also is worried about using up his wooden match-sticks. He is also angry about Mala having bought two tins of salt. Artie has enough of him and leaves for some fresh air.
