In 1984, President Ronald Reagan designated July as National Ice Cream Month and the third Sunday of the month as National Ice Cream Day. He recognized ice cream as a fun and nutritious food that is enjoyed by a full 90% of the nation's population. In the proclamation, President Reagan called for all people of the United States to observe these events with "appropriate ceremonies and activities." In 2009, National Ice Cream Day will be Sunday, July 19.
I found some ice cream t-shirts and ice cream gifts from some of the great designers at Zazzle.
