Can you help me?  I'm trying to remember a cartoon that I saw when I was a kid - it was probably from the early 60s or late 50s.  It was a one-off (not a series) and possibly a Warner Brothers cartoon.  It was similar in look to "The Honeymousers" and also starred several mice.  I think the plot was a foreign (Russian?) mouse was visiting his American cousin and the American was giving the Russian a civics lesson about how consumerism works, why capitalism is good and why America is awesome.  I think it had a lot of scenes in a normal American city populated by people and the mice, although they wore clothes and could talk, were just mice sized.  I seem to remember that the Russian mouse was excited by all that America had to offer and the cartoon may have ended with the Russian starting his own business in America.  Does this sound familiar to anybody?  Thanks!
