Like Jerry, I'm in the dark. One that particularly caught my eye was "Any depiction of political, religious, violent or sexual content." Religious? Does this mean that Christmas, Easter, Hanukkah, etc. will no longer be allowed by anyone but the PO itself? Or are they referring to bigotry? If so, perhaps they could have said it clearly: No slander.
Will my stamp depicting The Three Wise Men be deleted because it's Christian?
That was my first thought, that "religious" would be we can no longer do Christmas stamps. I hope that's not the case.
