Question: Why doesn't this Hallmark article mention that Hallmark makes all Disney greeting cards?

Answer: Because Gibson Greetings used to make all Disney cards, and Gibson was bought by American Greetings.

 Every day in every way, Hallmark and American Greetings are a MONOPOLY. And Wikipedia is being used by industry for purposes of mass deception on this page, the American Greetings page and the Sweetest Day page. It is that simple.
