I received this via email about the upcoming birthday of Britain's Queen Elizabeth II (note that I've edited it for length):
To celebrate the Queen's birthday this month (21st April), card and gift specialists Hallmark is asking Twitter users to tweet about the highlights of Her Majesty's reign (from the coronation to her Bond cameo) using the dedicated hashtag #HappyBirthdayMaam.
Tweets collected from this hashtag will then be used to create a unique personalised card for the Queen. What's more, three lucky winners will also be chosen from those taking part to win a year's supply of Hallmark Cards.
The competition will end at 10 am on Friday 12th April 2013.
Thank you to Hannah Craig at the Hallmark press office for sending this info. (The accompanying photo of Queen Elizabeth was also provided by Hallmark.)
