Whether you are planning to celebrate Valentine’s Day with your sweetheart or go the alternate route of Singles Day (China) or Friend’s Day (Finland), celebrations are in order during this time of the year and we all want to be prepared. While chocolates and small gifts are a still a good idea, nothing says ‘I love you’ more than well-chosen greeting card. Over 1 billion cards are exchanged every year in US alone. If you are a history buff with a penchant for romantic twists, you might already know that the habit of writing and sending cards goes back to Roman times and is tied to the name of Bishop Valentine, a priest who went against orders given by Emperor Claudius II not to perform weddings during wartime. For this, Valentine was imprisoned and executed. From prison, he wrote to his jailer’s daughter, Julia, and signed his notes “from Valentine”.
