Poster Stamp - Don't Let Newark Down - Pay Your Taxes!

I found this image on an ebay auction site a day or so ago and now it's no longer posted. Can anyone tell me any background behind such a Cinderella? Date? Reason for it? Were any other similar ones produced?



It seems to me that a Cinderella stamp to encourage citizens to "Pay Your Taxes" seems a bit odd for a promotional piece, but maybe it was more common than I realize from back in that generation.

"... or you will be getting a knock at your door!"
