Recently I have spotted "the number of the Beast" on several places...
According to the Holy Bible:
"Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is six hundred and sixty-six." Revelation 13:18 states that if one is wise and has an understanding to count the number of the beast, which is also the number of a man, the number comes to 666."
The first one is the logo of some Bulgarian supermarket... It is hidden in plain sight
The second one is the same way - hidden in the logo design of World Trade Organization
And the third one - a box of chocolates, that we bought on some occasion...
