This is apparently a real post card from Buffett according to Fortune magazine. Buffett did comment on it so it’s real.
Notice on the list is the stock Google! Charlie Munger has spoken very highly of GOOG in the recent past and Buffett has become less anti-tech (with his $10 billion+ purchase of IBM) so who knows.
Anyway, I too think GOOG is a good stock; I have posted on it here before.
