The Widow’s Mite Booklet

Well, then it all seems very clear to me, said Vetinari, sitting back. It is not often a mortal man achieves such a moment of glorious epiphany, but I am assured by the priests that such a thing could happen, and who should know better than they?  Anyone even suggesting that the money was in some way... obtained in some wrong fashion will have to argue with some very turbulent priests and also, I assume, find their kitchen drawers quite impossible to shut. Besides, you are donating money to the city-". He held up his hand when Moist opened his mouth, and went on, "that is, the Post Office, so the notion of private gain does not arise. There appears to be no owner for the money, although so far, of course, nine hundred and thirty-eight people would like me to believe that it belongs to them.  Such is the life in Ankh-Morpork.  So, Mr Lipwig, you are instructed to rebuild the Post Office as soon as possible.  The bills will be met, and since the money is effectively a gift from the gods, there will be no drain on our taxes. Well done, Mr Lipwig.  Very well done.  Don't let me detain you."
Once the stamps were being produced and the Post Office functioning again, the convocation of priests suggested that some stamp or stamps might be produced for the exclusive use of their various congregations. After all, prayer had been seen to work, and not ones to stand in the way of progress, after progress was no longer new, the postal system could be a boon to the worshipper in a hurry, or unable to attend the temple of their choice. Consequently the Post Office introduced two stamps which it felt covered the religious spectrum.
The first issued was 'The Widows Mite' a small black stamp, block printed and bound into small booklets that would, for a modest sum, deliver any letter or card that carried a written prayer or supplication to any temple in the city.
Booklets came in one of five colours with the front reading 'Ankh-Morpork Post Office 7+1 Half-Farthing Stamps One Penny Neither Rain Nor Snow Nor Gloom of Night' on the front and an advertisement for The Golem Trust on the rear. The Half Farthing stamps bear an illustration that very much resembles Durer`s Praying Hands etching.

The Penny Prayer Sheet

The same stamp design was revalued and revamped for the Penny Prayer sheet. The stamps were intended for for calling on divine intervention for the communication of special import that must get through. Of note is that these stamps are printed by Cripslock whilst the Widows Mite stamp were printed by Teemer & Spools. I have to say that the change of printer produced better quality stamps. Collectors needed to obtain these through the Green Cabbage Trading Scheme.
