In attempt to prevent high-risk drinking at 21st birthday celebrations in the United States, several public health studies have used birthday cards to try to modify drinking behavior. A 2009 survey of the attempts "indicated that the birthday card intervention was not successful at reducing drinking or consequences". == History ==

Wooden tablets found at Vindolanda on Hadrian’s wall, record an invitation, dictated by Claudia Severa, inviting her friend to a birthday celebration and they probably represent the earliest form of birthday card yet discovered. The mass-produced birthday card as we know it today, first made its appearance in mid-19th century Britain, shortly after the production of the first Christmas cards. == Notable cards ==
