Details: This poster shows a sparrow in front of a heart and red rose. In the middle it says Lucky 13.
The number 13 is associated with bad luck in some countries, and even has a specifically recognized phobia, Triskaidekaphobia, a word which was coined in 1911. In Sikhism, the number 13 is considered a special number since 13 is tera in Punjabi, which also means 'yours' (as in, 'I am yours, O Lord'). Several successful sports figures have worn the number 13. In Italy, 13 is also considered to be a lucky number. Colgate University also considers 13 to be a lucky number. In the Mayan Tzolkin calender, trecenas mark cycles of 13 day periods.
