What does PJD 777 mean on paul jr designs t-shirt?
The "7"s have a long history of being a lucky number. In the early days of Paganism there were 7 celestial bodies visible to the naked eye, and they were thought to be gods.
Other religions adopted this: The Egyptians worshiped 7 gods, Persians had 7 sacred horses, Islam teaches about the 7 heavens, just to name a few.
You might even think of the winning hand in Blackjack, 21, made up of three 7s! So it all means good luck to his company.
