No - sorry Tamar. This is something we cobbled together purely for fans to play with (as a kind of card school with the other Discworld board games) for the UK convention in one of the venue rooms last year. We've not got any permissions/authorisation to distribute these in any way including and especially on a commercial basis. We just took 4 complete decks along to the 'Dicebox' room every day during the convention and had 2 tables going most of the time for up to 7 players a game and shared the room with the makers of Ankh-Morpork and Guards! Guards! who were holding ad hoc tournies for anyone who wanted to play a game.
I can let people have sets in PDF format to print up and cut themselves (you can do this on any home printer using 210gsm or better thick card). Go here
for the 2 types of decks (traditional casino-style 13 card suits or Witches Abroad style with 8 number & 4 court cards per suit) and a choice of back designs. PM me for the PDF with your e-mail contact and I can get it off to you more or less by return
